Would be disappointing if he's the solution to our problems. Give him the chance if need be, but I honestly believe we need to get better than that.
I'd have no idea to be disappointed or not if Wilson stays and is part of the squad foe 2019/2020. He looks a tidy player for Derby though there are some concerns about his fit in our system. I've seen him compared to Maddison and Brooks. I personally don't think he is as good as Maddison at Championship level. No idea about Brooks since he went a bit under the radar for me.
What I would say is that I don't think there's a realistic scenario where Wilson stays and we buy another front 3 player. It's one or the other in my opinion.
I think Salah, Firmino, Mane, Origi, AOC, Brewster, Shaqiri will all play some games as part of a front 2 (442), front 3 (433) or front 4 (4231) next season. Though AOC and Shaqiri could play games in other positions also. Maybe AOC more so.
Wilson would be a 7th option for those forward positions. I don't see a situation where we buy another wide forward and keep Wilson. Unless we sell Shaqiri or Origi. It would be interesting if people would rather have Wilson over Shaqiri or Origi if given the choice.
I think the club would probably like to loan Wilson again. I think the Q might be whether Wilson wants to be loaned again.
