Still think this ship has long since sailed in regards to getting him this summer. From Arsenals perspective, they can't possibly let him go now after saying all season he's staying and not bringing in a replacement. They'd be riots and it would completely destabilise their season already. Wenger or the board, or possibly both would be under extreme pressure.
If they were going to sell him this season, they'd surely have done it early in the summer before they came out time and time again saying he's staying and whilst there's plenty of time for Arsenal to sign a replacement and probably most importantly plenty of time for Arsenal fans to simmer down.
I'd be delighted to be wrong but i find it very hard to believe
