I met with a season-ticket- holding Fulham fan today. Asked about Wilson, he said he blows very hot and cold, and this season is an unusually-long hot streak. Top scorer at the moment with 8 goals.
As a free transfer, he's probably worth a crack but I'd also be looking at J Rowe* to share wide duties (assuming all of Bailey, Sancho and Guessand do one). I'd also get a couple of our young wide lads into the squad to build depth and experience.
* Rowe is young, has had good and varied experience and could be developed into a Doku type player.
