Can't blame Manchester United for losing the game against Sevilla.
They had a good performance and they could easily win the game but the reason for Manchester United losing that game was mostly that they had many personal mistakes against Sevilla and especially the defenders were totally disappointing otherwise we could see Manchester United playing in the final match instead of Sevilla.
The mistake of the Manchester United defender was made very often in the last season, but Erik ten Hag really had no other choice but to include the player due to the mass injury that Manchester United faced. Manchester United should have won the match and in general the Red Devils squad was far ahead of Sevilla, only this time luck was not on Manchester United's side so they had to fall before moving on to the semifinals. Erik ten hag must be firm with every player and he must raise his voice for his players so they can be more disciplined in defending.
