You can lie to yourself but I can name more than 10 goals we conceded because of ''his lack of physicality'' alone in the last 2 seasons.
19/20 vs Palace (H) Ayew goal
19/20 vs Southampton (A) Vestergaard goal
19/20 vs Sheffield United (A) Their 3rd goal
19/20 vs Southampton (H) Obafemi's goal
19/20 vs Chelsea (Wembley) Giroud's goal
20/21 vs Palace Townsend's goal
20/21 vs Palace Zaha's goal
20/21 vs Everton Bernard's goal
20/21 vs Sheffield United McGoldrick's goal
20/21 vs West Brom Diagne's goal
20/21 vs Aston Villa Traore's goal
If you believe those goals are due to any lack of physicality or strength, then I can understand you see this type of goals goals everywhere.
Just look at those this season:
20/21 vs Palace Townsend's goal
Lack of physical ability? For not stopping the cross? Well guess he is partly at fault for that goal but wouldn’t say it was lack of physicality.
20/21 vs Palace Zaha's goal loss
Dribbled or poor balance maybe, but lack of physical ability? No.
20/21 vs Everton Bernard's goal
Partly at fault for this goal
20/21 vs Sheffield United McGoldrick's goal
Lindelof
won the aerial duel but headed it in the face of McG. How could this be lack of physical ability?
20/21 vs West Brom Diagne's goal
Agree due to physical ability although a clear foul
Poor defending maybe but not due to physical ability
So 1 goal fully on him and one partly on him coming from poor physicality.
The difference is that those other CBs take responsible to get involved in physical battle. Lindelof doesn't!! If he gets involved as equal as Maguire in physical battle, he would lose so much more than he's done now. Stop hiding this fact and twist it to make him looks better than the reality.
How many times we ask our-self why a small guy Fred or player who is not good in header like Rashford chose to try go toe to toe with physical players during corner kick while Lindelof marking the smaller player or players in less dangerous area? May be if Lindelof is good physically, he might take Rashford or other player's spot to get involved more in physical battle in more dangerous area/zone and we would be much more secured.
It’s zonal defence. You can read tons about it on the forum or elsewhere to learn more about it. Maguire and Lindelof are positioned on the line and AWB, Fred and Rashford further out.
