There are bigger "cloggers" than Kolo in the squad. I agree that we need to do better, but when his job is as last choice centre back there for emergencies, he's been arguably our best centre back this season. So he's done his job, it's the other two or three that are in front of him that need to be looked at first. Bring in a couple of first choice defenders, fuck off a few of the players who've failed to live up to their transfer fees and reward those that play well.
The lad has been a pillar of professionalism and has performed well too, he also looks like he genuinely gives a shit about the club and it's results.
It's not "cloggers" like Kolo that are symptomatic of our position, it's ever-presents who can't string more than a couple of good performances together.
