To be honest I don't know Nkunku well but from what I do know he's another one who plays behind a main striker (that we don't really have for next year unless somebody is counting on Aubameyang to be that guy.
We have two classic wingers, who aren't really performing. If I have to bet, one of them won't be here next year.
We have one Striker who is way over his peak and got booted by a team we used to miles ahead of. Now the tables are pretty much turned.
Nkunku could be a great player, is he what this club really needs? I don't think so.
