I agree with that, because if their defense were strong enough, they probably wouldn't have conceded 54 goals in a single Premier League season. And in that season, they conceded more goals than they scored. Manchester United is indeed filled with expensive players with high salaries, but unfortunately, their performance and achievements don't match it.
And what really bothers me about Manchester United is that a few seasons ago, they replaced their best goalkeeper, David de Gea. Because De Gea had made several blunders in several matches, they replaced him with Onana. But in reality, since Onana arrived at Old Trafford, has Man United's goal really been safe? His blunders have probably been countless. Now, David de Gea has returned to his best form, he's been performing well in goal for Fiorentina, and surprisingly, Man United wants to bring him back to Old Trafford.
Furthermore, there are already quite strong rumors that Man United will bring in Emiliano Martinez. Hopefully, this deal can be finalized.
Let me start with, Ten Hag was never wrong trying to look for a new goalkeeper because De Gea was never the actual solution to an evolving team. De Gea was actually having blunders those season and even before Ten Hag could come, and change was needed most especially when the game was evolving and a sweeper goalkeeper was needed. During that period of search I can recall that Onana was at the top of his game. Played the champions league final and was heavily praised by even Pep Guardiola then and Manchester United going for him wasn’t bat but the problem for me was allowing De Gea to leave. I believe with both players still in the club there will be heavy competition between them.
I can recall thd competition then between De Gea and Romero, it was good for the club and that was what was needed. I could remember Mourinho replacing legendary Casillas then with Diego Lopez but both were still in the club and this is how competition will have been created. Currently Onana looks relax without competition and that’s is making him to keep making mistakes without correcting them but if he stays long on the bench now he will certainly get his head back into the game
