In terms of play, Manchester United were indeed able to perform well and create dangerous attacks, but the carelessness of their own players made everything fall apart. Casemiro's red card gave Galatasaray more freedom, but Onana's poor performance was also the main cause of the defeat.
Onana's performance is really poor, his poor performance is really affecting Manchester United's performance. Onana was too hyped when he was about to be signed, but unfortunately, his performance is really poor. I just hope he will be able to improve his performance, or it’s really going to have a negative impact on Manchester United's performance. Manchester United's defense is also weak, that’s why Onana's weak performance is kind of obvious. If their defense is strong, they will be able to defend some balls that won’t get to their goalkeeper, and they will be able to cover up for Onana, so ten hag have to work on his defense and goalkeeper.
Actually, three goals from Galatasaray is not totally mistake from Andre Onana,
We all know that Onana's performance has been really poor since he got to Manchester United, United conceded 3 goals against Galatasaray. Everyone is blaming Onana alone, and they are not talking about Manchester United's poor defense. United’s defense is really weak, which makes it very easy for opponent teams to penetrate. United are always dominating matches, but any opportunity that their opponents have, they are always converting it into a goal because United’s defense is always easy to break.
