What makes him a good defender?
His best season with us was probably 20/21. But he was still not very good. Neither on or off the ball. In terms of «ball recoveries» for fullbacks he was in the 29th percentile in the PL. Meaning 71 % of the fullbacks in the PL made more recoveries than him. In my opinion, probably a reflection on how poor his positioning is.
His best asset was probably his «one-on-one» defending. And while his last ditch tackle is still great, he got figured out. He was in 20/21 in the 78th percentile with 52,5 percent success ratio. Good, but not great. And when he got figured out, he started losing his confidence more and more and became less aggressive (also a part of the game I appreciated).
He also really struggle to learn. He still dont have a clue how to defend a cross from the left side of the pitch.
Lindelof is ten times the defender he is. If Conte, Pep or Klopp had to chose between the two of them, there is not a chance in hell they would have picked AWB. Even if it meant they had to play Lindelof at RB.
