There seems to be a good amount of Juve fans that want to keep him. I don’t get that. Why? He showed nothing and has been unprofessional on top of it. If another club actually wants to buy him we should be thanking them.
Football fans love a bit of recency bias. He shows some nice touches in a friendly, maybe we ignore the previous season and give him another chance.
We don't know what has gone on behind the scenes with him but his main issue has been his lack of availability, doesn't matter how good you are if you can't play and integrate into a new team and league.
There might be a scenario in an alternate reality where he came in and looked like a 50m player, I agree that he has the talent (based on watching him at Villa), but sometimes things just go this way. I think we'd be foolish to gamble sticking with him in the hope he turns it around, rather than cashing in while we have the chance. He might do great at his next move but personally those things don't bother me, you can only deal with a player at your club and their circumstances, not things that happen elsewhere.
I also feel like we already have one reclamation project on our hands with Koopmeiners, who the club seem to have faith with, and can't afford to do it with two midfielders.
