If he was going to sign a new deal he would have done so by now. No he wants off, and as you say preferably in January. But I just cant see the likes of Chelsea and Spurs taking a chance on how he recovers from what looks like a very bad injury, especially when he is available for f'all in the summer. He won't want to go anywhere else plus there's also the chance our valuation won't be met.
I can see him being with us for the rest of the season. If he plays and is seen to be putting the effort in (and positively affecting results which always helps) then I don't think the fans will be too hard on him. Of course he may stink the place out too which is a high probability seeing has he's hardly kicked a ball since May.
Arsenal are in the same boat with both Sanchez and Ozil and they don't appear to be getting much stick. And Arsenal fans are bigger moaners than us, allegedly.
