Wilson has the potential to be a very good player. Injury set him back otherwise I believe he would be a regular starter, imo. f**k alone knows why Alessio won't play him.
Mulumbus gone. El Makrini looks the part but it's early days. I think he will turn out to be a good signing. Dicker has been one of my favourite players for a while and Power was outstanding last year. Him and dicker are getting on a bit and we have a talented replacement for CM in Wilson. He'll be let go though, to be replaced by loan signing no doubt.
I wouldn't drop anyone right away, but with the threadbare squad we have at the moment I wouldn't be telling him to find another club.
