The contract extension has been offered since the last summer and so far Pogba refused to sign it. If he has no intention to sign it then I dont think he will in the future so if his contract expires then he will be able to leave the club for free and I bet there will be alot of top club willing to take him in. Its safe to say that he is probably already having some clubs in his mind right now but anyway the team doesnt really need him though
He has been injured for quite some time and the team is doing quite decent even without him
Until now Pogba has not decided and even seems to have no intention of continuing his contract with Manchester United even though he has been offered various clauses by United on the grounds that his salary does not match and wants to add a salary to his job.
On the other hand, talking about the future until now, Pogba is still widely associated with Madrid and his former club, Juventus and there are even some sources who say that he has told his agent to find time to talk about his future at Juventus.
Ralf Rangnick has given the green light if Pogba wants to move to another club, because according to Rangnick why keep players who no longer
have the desire to play at Man United. But that doesn't mean Pogba is not worth keeping, if Man United want to keep a player there must be
a desire from the player to stay too. So according to Rangnick, Man United doesn't need to convince Pogba to change his mind. Leave Pogba alone
to decide whether he will stay or move to another club. Man United will also only sell Pogba if Pogba asks to be sold to another club, otherwise
Man United are still open to discussing a contract extension with Pogba. It seems that Pogba is still waiting for a team that dares to offer
a big salary, therefore Pogba has yet to decide his future.
