Personally, I've always been pretty impressed with Haidara. We all know he's raw but he's ample backup to Santon, a lot more so than Dummett I reckon. It's just a nice problem to have 3 young and decent leftbacks at the club right now.
Santon seems like he'll never be surpassed unless injured, so I do agree with getting one of the others a short term loan at a championship club at worst.
I'm one of Colo's biggest fans but he wasn't up to it in the last game, therefore Mbiwa should replace him......although we may need his experience against Manu. It's a tough call but it's all down to whether Colo's head is right for the match, which is obviously very doubtful lately. I have a lot of faith in Mbiwa, he's been mostly great since his arrival.
