In what games?
Nothing that suggest very suspect at all, trust me, one would noticed, like one noticed at the start of the season how very questionable he was in his performances, but since we changed to 4 man defence and Kwadwo been injured, he has done his task as LB with little to criticize (except the Sampdoria game), nothing to praise either, but defenitely not very suspect. It sounds like you are just searching for reasons to complain about him, I would have prefered if we hadnt signed him, but its best to keep critic fair and as objective as possible. Based on current performances, nothing suggest we should replace him this January.
