I think he should send him out on loan, because he isn't going to get a game the way his form has been lately. It might be the chnage will put his mind back on the game and away from his injury.
There isn't anybody else like him on the right side a flying and on form Carlos would be a big asset.
Miller should be gone by now, never mind in front of him, even if he is off form.
Keane's judgement on players is suspect, he certainly sees things I don't in a few, they must do it in training but never in the match.
