I think a lot of people had really high expectations from Onana when he was brought in. As these expectations haven’t been met, they would be quick to lay all the fault on him whenever they concede a goal conveniently ignoring that it takes the whole team to either win or lose.
I know Onana has a lot of potential and even Ten Hag despite all the goals conceded, still has faith in him. I do think Onana is unjustly faulted for their losses. Would they also fault him for not doing enough in aiding to score goals to win games as well?
Man United do need to step up their game. Poor performance even in the EPL.
When a team is out of structure, it influences the major players in the club, from the defensive line to the front lines. Manchester United has struggled this season, obtaining zero points in the UCL and currently sitting 10th position on the EPL table; nonetheless, the Red Devils could recover in due course. Erik Ten Hag senses fire in André Onana, and this is one of the primary reasons he selected him from Inter Milan as a backup replacement for David de Gea, but it's extremely terrible to see the new goalkeeper's performance deteriorate. He has conceded numerous goals as though he was an average goalkeeper in a mediocre club.
Honestly I can’t fault one player and not talk about another. The whole team has a problem of 100% fitness but every fan is looking for a scapegoat. I don't think even Casemiro who was one of their best player last season is playing better now. Look at the number of balls Fernandes looses at in midfield, Dalot's errors, Rashford who is out of form and players who can't fall back to cover. The whole team is dysfunctional and Ten Hag has refused to find solution to this.
