He has put in much better performances this season in the chances he has been given than Clichy did before his injury.
Clichy is frustrating as shit as he holds up play on breaks and passes backwards or to the side when hes meant to push on, if someone's in front of him he will bottle it. I'll feel a bit gutted when he returns to be honest.
Kolarov puts in a lot more assists and balls than Clichy ever will and his stats prove it, Clichy actually provides very little to goals, he's a very reserved defender. In the BPL games Kolarov's played thus far he has done a good job in defence, I can't recall an instance where a chance was made because he wasn't in position.
