Yeah, it's the centre backs job.
The key to a successful defence in the Chamionship is complete organisation, everyone in the back four must know exactly what their job is and they've got to be very discplined. Not only did Bamba make it difficult for himself half of the time, by running off into the opposing half, or trying to dribble his way out of the box with two or three opposing players round him, he made it difficult for any other defender to play with him. How can you defend well when you have no idea what your defensive partner is going to do next?
Bamba is undoubtedly a talented footballer and he was certainly entertaining to watch on occasions, but his complete lack of tactical discipline means I won't be sad to see him go. I prefer midfielders and strikers to provide the entertainment, while I prefer defenders to be an absolute solid unit. I take much more pleasure in clean sheets and victories than the sight of one of my team's centre backs trying to dribble the ball into the opposing half. You're not Beckenbauer. Do your job properly.
