There is not surprising about the decision of Manchester United to either loan Onana or sell him out because he is aware that he is not doing well as a goal keeper for the team, Manchester United is looking for a way to offload him since they have gotten a new replacement for him but they are not going to determine where the player should go it is obvious that the only club that is interested in the poor performance of the goal keeper is the Turkish team and the team will accept the offer if they meet up to the demand. Onana has the right to reject the move but you already know what he will become at Manchester United a bench warner.
The Turkish Super Lig transfer window is still open, so it makes sense why Manchester United is using it to push Onana out. Besides, Manchester United has also signed another goalkeeper, Senne Lammens, so at this point Onana might not have any other choice. In my opinion, Manchester United is trying to get rid of Onana subtly.
Ruben Amorim will clearly give more trust to Altay Bayindir and Senne Lammens in the future, and it's a sure thing that Onana will be on the bench all season. It's very likely that Onana will agree to the loan deal, and perhaps with Trabzonspor he can rediscover his best form.
