But Onana is a good choice although I think that the defense in general hasn't been doing very well. I think when you have some weak players, it also makes everyone else less confident.
Apparently, David Gea is one of the best goalkeepers in the Premier League, and his club status is pretty good. David Gea has a lot of experience compared to Onana. But one thing is a key factor in performance: age. In addition, if you become old, you will definitely be lacking in your own performance status. Similarly, this happened to David Gea. He has a lot of experience and a brilliant ability to hold the ball in the net for Manchester United, but unfortunately, he became old and his performance is not at their prime level. Onana is young, and he has the ability to defend a goal. So in my perspective, it is the right decision by Manchester United coach Ten Hag.
David Degea and Andre Onana have their own abilities, hopefully they will both achieve achievements at their respective clubs. It's as simple as this, there is a time for everything, Dee Gea has probably been guarding goal longer than Onana, maybe D'gea's time is running out. However, regeneration of goalkeepers continues to emerge from academy graduates, therefore ETH will probably use Onana who is fresher in terms of age and tempo of play which suits ETH, both of whom are equally good in their respective eras.
