In my opinion there isn’t much to think about because the only reason they have to be thinking about this is because Amorim has not signed a new goalkeeper, once United make a new goalkeeper signing I believe he will be pushed straight into the first team and as first choice goalkeeper then either of the two present goalkeepers will need to leave but until then anyone can start any game, it has not been decided who is first choice.
Without a doubt it's obvious that Amorin has lost faith completely in onana, so as long as Bayindir A. stay out of stupid errors at goal, he will be maintained as the current number one goalkeeper of Manchester united till a new goalkeeper is signed which I think is very much unlikely considering how much the club has already spent and how they are trying to sell off some unwanted players in other to balance their books, so I believe that if Bayindir A. stays out of errors and he can continue with his brilliant performance at goal like the Fulham game yesterday, he is going to be a man stay in goal for Manchester united.
