Wenger loves the club (and the control he has) to just walk away when his contract expires and i dont expect him to leave for good. I think they'll offer him a job of some kind and probably let him have a say in who comes in for him.

Right now, someone like Martinez would be good but he has only shown potential so far and the next couple of years should tell us if he is the real deal or not. Not too long ago, the likes of Coyle and Phil brown were manager of the season candidates but where are they now? it can all turn around ina year or so.

The likes of Klopp, Guardiola, Conte, Simeone however have shown consistancy and the ability to win major titles and anyone of these would be a real coup.
