There are rumors that Andre Onana will transfer to Trabzonspor in Türkiye. Trabzonspor isn't a very high-quality team, and there might be better options for Onana. He could achieve much greater success with many other teams in Europe.
I think Andre Onana needs some breaks from the high pressure at Manchester United. The club isn't even doing any good and this is declining Onana form very much. He needs to move to another club that has less pressure but I don't want him to go to a poor league. He's still a decent keeper and needs some motivation to get back to his form. He was once a top keeper that had clubs coming for him. He should maybe switch back to la liga and become a backup goalkeeper instead of going to a league that nobody will hear about him again. Manchester United have really killed many players careers because of the poor management of the club and onana is an example.
I don't think any top team will come to sign Onana at this point, Onana's performance is so bad that everyone knows about it, if Manchester United wants to sell him, they will not have any good offer from any club, Manchester United signed Onana for about 45 million, if they want to sell him, no team will offer that price, some teams will not want to pay 20 million for Onana because of his recent performance and how Manchester United wants to get rid of him.
The only way Onana can leave Manchester United is if the team accepts any offers. Manchester United can still keep him on the bench or send him on loan, but the way things are going, it shows that Manchester United does not want Onana to be a part of the squad again. Over the last three to four seasons, Onana has been one of the best goalkeepers in Serie A and the Champions League, and now he is a player that Manchester United wants to get rid of immediately.
