Kolarov is a good player, but not the kind of player we all seem to want now. He has bailed us out of numerous holes, not the least of which was converting to a solid left sided CB last season.
There have been a few high profile incidents that some people like to use to say he is wank. Absolute garbage "analysis," because it completely ignores the fact that he was the prototypical "flying full back" who was doing what was asked of him by his manager and getting hung out to dry by the weak link left winger who gave away the ball at the end of his lung busting 70-80 yard sprint down the line. That is what a midfielder is for...to cover for him when he makes those runs, but apparently that guy gets away scot free?! As does the winger who gave the ball away!
Over his time at City, he may have lost a step, but he was never the fastest player, but has been fast enough 99% of the time. We do him a disservice to act like he is, was and always will be wank. He hasn't and I thought City fans were better than that.
In fact, I'll go one further. Apart from the level of "heart" shown and willingness to put his head in where feet and elbows are flying, I think he has been a better, faster and more complete full back than Zaba, whom I admire greatly.
