Not convinced by Kolorov at all. For his size he does not win the ball in the air, he is not the best tackler and he lacks the pace that full backs need. Yes, he has a decent delivery/cross on him, but the attributes I look for in a fullback he lacks. We have performed well defensively as a unit over the years in spite of Kolorov not because of Kolorov. I lost count yesterday at the amount of times that Ottomendi was pulled from left side CH to cover at left back for Kolorov. I think Kolorov is 2nd only to Yaya in lack of effort tracking back and he's a defender. As a squad player I think he has value, but I don't think he would make any of our title challengers first team, whereas players like Hart, Kompany, Ottamendi, Silva, Fernandinho, Yaya (in the right system) KDB Sterling (?) and Aguero all would. Of our FBs Zabba, Sagna and Clichy all have their strengths and weaknesses, however I would have all of them in my team over Kolorov. Let's not forget Kolorov cost us 16-18mln. More than double the other three combined...so it's not like he was cheap. We paid good money for a LB that has been serviceable. A great LB he is not.
