Currently, Manchester united defense is the major problem that they are having since Ten Hag time till date. This is why you see that sharp attackers breakthrough easily and find the back of the net, United should be happy that Onana is always confidently waiting on his spot to stop any ball coming into the goal post. A lot needs to be put together in the team starting from the defense to the strikers.
Well, this is what I understand from the weaknesses that Man United has that will later be fixed by Amorim. Even before I also said that there were several defenders who made the performance of the defensive line bad and I'm sure Amorim already knows who will be replaced with new players.
It would be a waste if Man United had a strong attack line but a defense that is easy to break through. So there is no balance between the front line and the back line which causes the performance to be less than optimal.
And I was also disappointed when De Gea was fired and replaced with Onana who I think is much worse than De Gea.
