Give Onana more time to adapt well, he only has 11 games with Manchester United. There are players who immediately fit into their new team and there are those who don't, so let Onana adapt well for his first season and see what he can prove after that.
At this level of the game he has had enough time to adapt to the team. Playing between the sticks and as an in-field player are two different things and requires different levels of adaptation. A goalkeeper does not have to adjust to much besides having his team get used to how they play out of the back but he does not have much to adapt in term of shot-stopping.
Raya at Arsenal did not spare anytime to get used to playing, even with his risky play out of the back and has not had much errors while playing.
Different players but Onana needs to get up to speed and not cost the team much points.
