I can't believe it. I can't believe to see how MU tries to send Onana to the club that is none know about. It seems to me club has no trust on him, and wanna get rid him off the club. If it was La Liga or Serie a, i'm find. However, they wanted him join in the Turkish league club.
I expect rejecting this offer may make Onana gets seat belt on his bench. It's obviously dilemma for him whether to stay but get no minutes or leave with the possibility to stay there forever.
This is a good move for Man United, as he can't be expected to replace De Gea. It's only right that Man United let him go if they want to make a change for the better, as Man United problem lies in their weak defense. Furthermore, even if he stays at Man United, the club won't necessarily use him, as Man United have already signed a new goalkeeper this summer, so competition for places is quite fierce.
I think La Liga and Serie A clubs should think twice about signing Onana, as he no longer possesses the same abilities as he did at Inter. His quality has clearly declined, so rather than waiting for clubs from other leagues, it's better to accept offers from Turkey.
It seems more logical to me that he accept the offer in Turkey, as the competition is a bit easier there than in Europe. He could improve his statistics a bit and join a better team this year and next. Trabzonspor sold their own goalkeeper to Galatasaray for a very high transfer fee. With this income, loaning Onana from Manchester United made perfect sense for them. This way, they've added an experienced goalkeeper to their squad, just on loan, and solved their goalkeeping problem. We'll see if the player accepts.
