I think it has everything to do with Emre Can leaving. I think Keita replaces Can in the midfield. With coutinho going it also brings money in and is another high wage off of the bill. With Can looking likely to leave it would be good to get him now, get 6 months playing with us under his belt so he can fully step in to replace Can in the summer. I think there has been some positive talks recently with Can to do with his contract which may have made us rethink getting him this window. I think Can might have signed a new contract with us.
So Keita is supposed to replace Can but we want to negotiate with Can for him to stay. Hm, I need some time and probably won't understand that nonsense
