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.
I remember Matic's words, he said Onana was one of the worst goalkeepers in Man United's history and in that match it was proven what Matic said came true. Of course it was very bad, the victory was in sight then with the mistake made by Onana at the end of the match because he could not secure the ball properly so that the ball was taken by the opponent, Man United lost important points. Indeed, Man United still has a chance to qualify, but this draw makes Man United have to work extra in the second leg later.
Onana not only made mistakes in the Europa League but also in the EPL, but Amorim did not learn from his mistakes, he always made Onana a core player. If Amorim does not rotate in the second leg, Man United will have difficulty qualifying. In my opinion, Onana should be sold or loaned to another club like Anthony and Rashford, before he forgets how to be a good goalkeeper.
