At the end of the day, he has 2 years left. Champions league is still possible this season, Europe league very possible. If we get champs league, he will be happy. If not and we keep improving at rate we have this season, top 4 is more than possible next season.
Him signing doesn't change a lot. Refuse to sell him this summer and don't offer him anything else. If he wants to move, he has to play and play well next season and could result in us getting champs league. If he does a payet then he is a snake and just treat him like niasse got treated. Yeah, selling him will give us a big lump sum, but him firing us into champs league has longer term financial benefits. Just don't sell him and make him play another season and then see where we are. If he still wants to go, then sell him. But the 2 years he has left is vital as we can still get a year out of him where he has to perform to get a move to a top club.
If all else fails, [Poor language removed] him, we will have niasse
