Personal opinion was that Kolarov's best season was Pelles first but he has been pretty mercurial most of his time here to be honest, when things go well he has looked good on a number of occasions but when things have been poor...................Pretty much, he's bigger and faster, a much better defender. Attack wise he's not as good as Kolarov at his best but I always felt we didn't see kolarovs best all that often post-Mancini.
