Lastly, as a neutral fan, when watching this Manchester united team, I feels like they are very light in midfield in terms of quality and depth, because I don't see any competent defensive midfielder in the team that can replace casemerio if he go injured or he is on a suspension, so I think that this their midfield is really going to be one of their major problem this season.
I don't see Casemiro's job in the Manchester United squad, how did he help them to know there would be trouble if he got injured? Casemiro isn't capable of making a decent pass, he consistently makes mistakes. I believe it is preferable to remove Casemiro from the squad than to make mistakes that will cause them to lose games, in my opinion, Ten Hag's is simply using him to complete as the eleven players on the field because he has nothing to give to a team anymore. The best choice is to sell Casemiro, as they have already bought a new defensive midfielder from PSG, who will be better than Casemiro and cause errors.
Better to put Onana on the bench and let Bayindir to play, he's always become goalkeeper for Manchester United while Ten Hag already try to rotate and change the players. But still, the performance is still same, as we know only Onana that has never get changed by Ten Hag.
I agree that if Ten Hag benched Onana, we might see some different changes in the team's performance. Since joining the team, Ten Hags has changed several players, and he hasn't been able to stop using Onana to give Bayindir a chance in a single game. In fact, I don't think Onana has missed a game in any competition, even Manchester City, who has won the league title for the past three seasons, has given their second goalkeeper a chance sometimes but Ten Hags has always believed in Onana. The fact that Onana is usually Manchester United's goalkeeper annoys me.
