If Sanchez didn't make mistake, Chelsea should've won this match. Hojlund wasn't in a good position to shot, even if he shot, there was James can block it, but Sanchez forced himself without thinking about the consequence.
Yes, we can see that Manchester United's game has improved a bit. After Ten Hag left, they can say that they have improved their defense a bit by adopting the new interim coach's strategies. Many of us thought that Manchester United would lose against Chelsea, but they didn't lose, but drew the game. They resisted Chelsea's strong attack and Manchester United performed quite well. I think if Manchester United can improve their game and become stronger, they will definitely be able to do something good by the end of the season. Yes, since Manchester United is currently moving in the right direction, they need to be patient and adopt better strategies if they are to move forward. Manchester United definitely needed a good manager to bring about change, which is what Man United has now and they are preparing to move forward at the moment.
Make sure people shouldn't ask to sack Amorim when he didn't bring good results during his first season. It requires process and consistency, like Pochettino need a year to transform Chelsea.
Don't expect to much for Manchester United in this season, as long as they're not relegated, they're fine.
