Andre Onana is a goalkeeper who is still very young, doesn't have much experience, and can be said to be immature because he still has points of gaps and weaknesses when the opponent manages to get a score from a kick in the middle of the field and break through Andre Onana's defense. Hopefully, in next season's match, Andre Onana will perform better and focus so that it makes it difficult for opponents to score goals.
Onana has not managed to show his best quality in guarding Manchester United goal in this pre-season match. But he can still develop well to show his best quality before the Premier League rolls back. Manchester United do expect Onana to be able to impress in keeping out many shots from opposing players in the next season because he has been burdened with a tough task after De Gea left.
I think fans will wait for the right moment to see the quality of Onana, because of De Gea departure some fans really regret it because De Gea is a pretty good goalkeeper that Manchester United had in the previous season.
