Onana has always been main goal keeper because of his team lack of proper goal keeper. So many fans urged Amorim to sign new goal keeper, and hopefully he's hearing all of feedback come to him.
Onana is not good enough as a goal keeper.
He always makes mistake that give draws in the match because he should have known that there was an opponent in front if the ball was not caught perfectly. So far there is nothing special about Onana because if you pay attention he always makes mistakes that have fatal consequences for the club and because of his mistakes I lost my bet on the match.
It is time for Amorim to make adjustments where Onana's performance needs to be rotated because if it continues like this it will have quite an impact on the results in each match because this is not the first time he has made a fatal mistake.
Almost a lot of people berate Andre Onana for poor performances because his mistakes make the club disadvantaged, it has already happened several times where Onana's mistakes have an impact on the club's victory which eventually lost. You shouldn't be surprised that their fans lost their bets.
Maybe Amorin can't do much at the moment depending on the manager's decision, but the rest of the season is now a little longer but after the new season it could be that Onana will be rotated after they get a decent goalkeeper.
This goalie likes to joke around and it would seem incomplete if he didn't make a blunder before the match ends. Onana may have had a good run at his old team, but I don't see him looking consistently impressive when he joined Man United. Man United has a goalkeeper on the bench, but it's strange to see only Onana on the pitch. As far as I know, Altay Bayindir is available and has recovered from his injury, but for some reason, Amorim still hasn't given him a chance to play. Even before the injury, Bayindir played quite impressively (against Liverpool) and I think he deserved more chances.
