Hard to say if Colo is EL class, as he's never played in the EL before. Odds are, he probably is.
This game is played with 11 guys, not 1. Lescott is better than all other City center-backs save Kompany. But he struggled last year in the CL, that's objectively true. Agger has proven a strong starter in the CL and he was downright brilliant for Denmark in the Euros against much stronger competition than Lescott.
