I think it's a big factor in Aston Villa's goals from outside the box this season When I watched back their goals from distance, almost all included a blocked sightline & a delayed goalkeeper reaction I broke them down in the thread below if you want to see more details! bsky.app/profile/tomh...

These were my results when I used StatsBomb open data to study the impact of players being positioned directly in-between a shot and the goalkeeper (so possibly blocking the view) Pressuring the shot reduced the xG, but possibly blocking the view, without pressuring, increased goal probability

Great piece Conor! The graphic showing a correlation between quantity of attempts and over-performance is an excellent insight Interesting that you mentioned defenders obscuring their keeper's line of sight as well- I've found that this isn't considered enough in xG models

🔹Conclusion 1️⃣ Berterame has adapted to different roles- he may be used as a wide attacker as well as the 9 2️⃣ He should provide an upgrade on Suárez's box poaching ability- without losing much of his linkup play 3️⃣ However there are concerns over his defensive work rate, creativity & runs in-behind
010
Tom Harrison @tomh36.bsky.social · 31/01/2026
❗ Re-discovering his ability to time runs in-behind defenses could be key to Berterame maximising his goal production in Miami 👇 As pointed out by @shelatneel.bsky.social- Tadeo Allende’s movement (& finishing) was crucial for Inter Miami in the MLS playoffs www.thetransferflow.com/p/can-lionel...

Tom Harrison @tomh36.bsky.social · 31/01/2026
❔ Can he rediscover his movement behind defenses? ▫️ Domenec Torrent has implemented a patient build-up approach at Rayados- often leading to them attacking lower blocks ▫️ Berterame hasn’t received many through balls this season 👇 But, he was able to do this more frequently in the past (deep runs)
100
Tom Harrison @tomh36.bsky.social · 31/01/2026
❓ Will his lack of pressing be an issue? ▫️ Defensive work rate is important to support Messi in the Inter Miami attack ▫️ Berterame hasn’t been particularly intense out of possession in recent seasons- although Monterrey don’t currently press much ▫️ Age factors may also have impacted his pressing
100
Tom Harrison @tomh36.bsky.social · 31/01/2026
🔻 He's also a less creative forward than Luis Suárez ▫️ Whilst Berterame has been more effective at getting on the end of chances than Suárez, he offers much less creativity for teammates ▫️ Berterame was more creative in a 2nd striker role, but not at the level of Suárez
100
Tom Harrison @tomh36.bsky.social · 31/01/2026
❗ However, Berterame will have to provide far more linkup passes if he's to replace the impact of Luis Suárez, and his connection with Messi
100
Tom Harrison @tomh36.bsky.social · 31/01/2026
▫️ Whilst he isn’t often an outlet for long balls, due to the Monterrey style of play, Berterame has been pretty effective in the air 👇 Good number of linkup passes per game, finding a teammate after receiving back to goal
100
Tom Harrison @tomh36.bsky.social · 31/01/2026
▫️ The change in Berterame’s role has particularly helped his decision making when shooting ▫️ Often a long-range shooter in the past, his xG per shot was below average for a Liga MX striker in 2022-23 🔺 In 2025-26, the Argentine has the 5th best xG per shot
100
Tom Harrison @tomh36.bsky.social · 31/01/2026
👇 Now, Berterame has a much more specific striker profile ▫️ The focal point of the Rayados attack, he’s consistently finished chances from inside the box, connected attacks by receiving back to goal, and won aerial duels
100
Tom Harrison @tomh36.bsky.social · 31/01/2026
🔹 An all-round forward transformed into a goal poacher ▫️ Berterame arrived in Liga MX as a wide attacker or second striker 👇 In 2022-23 he ranked at or above Liga MX average in all key striker concepts

Tom Harrison @tomh36.bsky.social · 14/01/2026
🔹 Conclusion 1️⃣ More runs into the box can improve Romero's xG, reduce his number of long-shots & develop his creativity by getting into cut-back positions, on the left-side of the box 2️⃣ He needs to shoot less often from range 3️⃣ Romero can improve his shot efficiency by working on his technique
000
Tom Harrison @tomh36.bsky.social · 14/01/2026
4️⃣ Reduce his number of blocked shots 👇 Another example below of a big set-up touch, large back-lift & a blocked shot ▫️ Romero shouldn't shoot from here anyway, he should get his head up & pass out wide, but the technique makes the defender's job easier
100
Tom Harrison @tomh36.bsky.social · 14/01/2026
4️⃣ Reduce his number of blocked shots 👇 Romero also uses a large back-lift when shooting ▫️ An effective technique for creating powerful shots ❗ But, the time between the set-up touch & the shot is too long ❌ Defenders have time to read his decision & react, leading to many efforts being blocked
100
Tom Harrison @tomh36.bsky.social · 14/01/2026
4️⃣ Reduce his number of blocked shots ▫️ Romero scored a few stunners from range at youth level, but his technique has proved unsuccessful in professional football, with less time and space 👇 He likes to take a large touch before striking the ball, giving him a bigger run-up
100
Tom Harrison @tomh36.bsky.social · 14/01/2026
4️⃣ Reduce his number of blocked shots ❗ Nearly half of Romero's shot attempts have been blocked ▫️ This is another argument for Luka cutting-down his efforts from range, but there's also a technical adjustment to be worked on
100
Tom Harrison @tomh36.bsky.social · 14/01/2026
3️⃣ Better decision making ❗ Romero shoots too often from distance 👇 His xG per shot is only 0.06 in 2025-26, amongst the worst ranked players in Liga MX, and his finishing from distance is a weakness ▫️ Romero's 4 goals have come from inside the box, he needs to cut down the shots from range
110
Tom Harrison @tomh36.bsky.social · 14/01/2026
2️⃣ Get the most out of playing on his natural side 👇 Romero is not a particularly creative passer 📈 But he could improve his xA with better movement 👉 By making runs into the box from the left-half-space, Romero should receive possession more frequently in cut-back situations, on his stronger foot
100
Tom Harrison @tomh36.bsky.social · 14/01/2026
1️⃣ More runs into the box 👇 It's important that Romero can penetrate defenses through his off-ball movement, given his lack of dribbling ability ▫️ With Paradela & Agustín Palavecino, Cruz Azul already have key, ball-to-feet, creators ❗ They lack off-ball runners, to receive the creative passes
100
Tom Harrison @tomh36.bsky.social · 14/01/2026
1️⃣ More runs into the box 👍 Luka showed an ability to get into the box and shoot from higher xG locations during his first season in Liga MX 👎 With fewer box touches in 2025-26, his xG p90 has dropped from 0.26 to 0.12
100
Tom Harrison @tomh36.bsky.social · 14/01/2026
▫️ The signing of José Paradela has also impacted Romero's positioning ▫️ Paradela, Cruz Azul's main creative hub, is more comfortable on the right side of the pitch- so plays as the right "10" in Larcamón's 3-4-2-1 👇 Romero has been shifted over to the left side, when he's received game time
100
Tom Harrison @tomh36.bsky.social · 14/01/2026
🔹 The context ▫️ The 21-year-old hasn't impressed since Larcamón joined as head coach for the 2025-26 season 👇 Romero only stands-out as above league average for his out of possession work

100
Tom Harrison @tomh36.bsky.social · 09/01/2026
🔹 Conclusion 1️⃣ Chivas need to better defend central, direct attacks to reduce their xG per shot against 2️⃣ More protection for Romo, who struggled in an aggressive role 3️⃣ A better rest defense & more intensity in the counterpress 4️⃣ Reduce turnovers with more patience & individual development
010
Tom Harrison @tomh36.bsky.social · 09/01/2026
🔹 A right-side weakness under pressure ▫️ Their right-center-back was another source of turnovers 👇 Both Campillo & Daniel Aguirre suffered when put under pressure & can develop individually ▫️ This clear weakness makes pre-match preparation easier for coaches looking to press the Chivas build-up
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
▫️ Luis Romo, a key part of their build-up, can improve his decision making ✅ Romo played more progressive passes, per game, than any other center-back during Apertura 25 ❌ But his verticality had a clear drawback, the high rate of losses p90
110
Tom Harrison @tomh36.bsky.social · 09/01/2026
🔹 More patience in-possession ▫️ Performance in defensive transition could be improved by cutting down the number of turnovers 👇 Their long ball % was above league average last season ❗ However, only 2 sides created fewer shots in direct attacks 👉 It's a high-risk strategy with low rewards
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
👇 Chivas rank poorly in many counterpressing metrics ▫️ Their reaction after losing the ball has been poor ▫️ This has allowed opponents to quickly move the ball into the final 3rd ▫️ Chivas also turned-over the ball more frequently than any other side that made the quarter-finals (liguilla)
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
🔹 Improve in defensive transition ▫️ Chivas haven't been as intense or aggressive in counterpressing situations, compared with regular opposition build-up- there are rest defense issues 👇 Many of the central, direct attacks faced by Chivas have come in defensive transition
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
🔹 Possible solutions ▫️ Milito could move Diego Campillo, 24, back into midfield ▫️ Campillo played more on the right of the back-3 last season, but could come into midfield as Chivas recover defensive injuries 👇 Milito could also give minutes to Brandon Tellez, who's part of Tapatío (their B team)
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
▫️ Omar Govea, 29, is the youngest midfielder to have played a significant number of minutes for Chivas last season 👇 Govea is talented on the ball, but isn't particularly intense out of possession
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
▫️ A lack of protection from the double-pivot contributes to the amount of active defending that Romo has been required to do ❗ Chivas lack an energetic & effective pressing midfielder 👇 Fernando González is a good holding midfielder, but struggles with a more active role, losing 3/4 of his 1vs1s
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
🔹 Luis Romo needs better protection ▫️ Romo, a versatile 30-year-old, has often played in the center of Milito's back-3 👇 He's been asked to play an active defensive role, often jumping to press opponents & contest duels high up the pitch ❗ Romo has struggled with this role & lacks recovery speed
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
👇 Their opponents also had success from direct attacks ▫️ Only Cruz Azul received a higher % of shots in direct attacks, but their xG per shot against was the 2nd lowest in Liga MX ❗ Chivas did force many attempts from range, but this couldn't greatly limit their overall xG per shot against
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
🔹 Central weakness 👇 The majority of opposition final 3rd entries have come from the half-spaces & central lane ❗ Only 29% of box entries against came via crosses, the lowest percentage during Apertura 25 ▫️ Chivas must improve their control of central areas to reduce their xG per shot against
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
🔹 The style of play ▫️ Milito has focused on the out-of-possession approach, with greater intensity in their press & a higher defensive line ❗ Their style suffers from a common weakness 👉 The press limits opposition box entries & shots, but their xG per shot against is high (4th worst)
100
Tom Harrison @tomh36.bsky.social · 09/01/2026
🔹 The context ▫️ Chivas had some struggles adapting to Milito's style at the start of the Apertura 25 season, before improving towards the end of the campaign 👇 Significant up-tick in xPoints after dropping below league average ❗ Playing the top 4 Liga MX sides in a row also impacted the trendline

Very true, and whilst it is a blindspot, it isn't hugely significant
000
Tom Harrison @tomh36.bsky.social · 29/12/2025
Absolutely, I see what you mean. Just saying his scoring rate vs xG is a bit exaggerated by models that don't consider that many of his goals have been helped by a blocked keeper sightline Like the West Ham goal wasn't that good a finish (not in the top corner) but Areola saw it late & reacted late
100
Tom Harrison @tomh36.bsky.social · 28/12/2025
I'm definitely not saying it's sustainable! But I do think the over-performance is a bit less than models suggest. He's scored multiple times when the keeper's sightline has been blocked, which results in more goals than models expect. I analyzed it in this thread 👇 bsky.app/profile/tomh...
130
Tom Harrison @tomh36.bsky.social · 26/12/2025
❗ Current xG overperformance doesn't seem sustainable, but there is a blindspot in the models, which could be underrating some Aston Villa goals ▶️ Now, defenders need to adjust their positioning in these situations, avoid blocking the sightline, to give their keeper the best chance of making a save
000
Tom Harrison @tomh36.bsky.social · 26/12/2025
❗ Whether by luck or by design, Aston Villa keep scoring from lower xG positions when the goalkeeper's sightline is blocked ⬆️ This partly explains xG overperformance, alongside work on ball striking technique, as described in this @greggevans40.bsky.social article- www.nytimes.com/athletic/683...
100
Tom Harrison @tomh36.bsky.social · 26/12/2025
🔷 Aston Villa coaches may have also trained players to identify these situations, & shoot when they believe the opposing keeper doesn't have a clear view of the ball ▶️ This may differ to some coaching ideas, which would encourage players to find a teammate in a higher xG position
100
Tom Harrison @tomh36.bsky.social · 26/12/2025
❓ Is this a deliberate tactic? Could it be? 🔷 Impossible to control the open-play situations- but they may become more likely by: 1️⃣ Consistently finding free players between the lines 2️⃣ Cutting the ball back to outside the box after forcing the opposing defensive line to retreat
100
