Do I need a slap? Or has Perch looked good as a sub CM in the last two games? He played his part in the goal at City, and I believe almost set up Ba for a goal vs Manure? He's crap at CB, but he's not that bad at playing 15-20 mins to help defend a draw or win.
He would have scored the most spectacular own goal you've ever seen if it hadn't been blocked in the last game.
Yes and yes Others have said he looks better there as well. Perhaps he is improving, but currently I think he's too much of a risk to be considered. I would rather move Tiote out of position to the back and get Colo to guide him than have Perch at CB. At CM I see no reason why we couldn't send him on as a CDM as you say, towards the end of matches, just to test him out and give him experience there. This would of course be saved for smaller/non-league fixtures though, when we are leading with a good margin. Ultimately, I haven't really seen enough of him to judge, just enough to see that he can't hold a CB role.
