I think it's a little bit different with Wilson.
Yeah he binned off Fraser, but they had history of Fraser been a little twat.
You can tell he has a very close relationship with Wilson, you could see at the end of the Everton game he looked a bit emotional towards Wilson doing his lap of honour.
I don't see any logic in offering Wilson a new deal, the only scenario it could be ok is if we signed a new striker and Osula goes on loan.
