They sold Onana to MU because they knew his development was stalled, and cashed out him for a bunch of money were the best. They will never ever sign his former goali back again to their squad. they have plenties of experienced young goalie available in the market. Why they need to re-sign Onana?
It's be pointless to bring him back to the serie a. He's happy at MU, and leave him there. Let MU to enjoy his service.

How do people come on here and write stuffs like this? He was stalled but was able to carry Inter Milan until the Champions League Competition finals against Manchester City? He was solid and the same time, had a good relationship with the management. That said, his move to Manchester United was also back by VanDer Ser who was one time Manchester United goalkeeper and legend. Anyways, United are still down for the signature 9f a younger goalkeeper.
