He's already good. Just get him playing in the ****in no 10 role where he should be and not a ****in lone striker.
Yep he's a good player,can spot a pass and played in the correct position can be a handful for most teams
No where near enough evidence to suggest we should be relying on him for anything though. Wilson is our main striker, and we need another one as a 2nd choice. When Wilson gets injured, I don't want to have to rely on Joelinton. I'd sell him for anything 5m+ or above, if not just leave him as 3rd choice.
