I know that whatever we discuss here may not be in line with Ten Hag's ideas, especially in formulating a game plan in a match. Technically Ten Hag has done his best so that his team can get into good form, but it hasn't worked for Manchester United. It's definitely not been a good season for Ten Hag, but I also don't discount the selfishness of some of his players in the game.
Marcus Rashford's performance was completely beyond expectations, I mean he is a player who has had a big downfall earlier this season. Marcus Rashford only scored 1 goal and 1 assist in 7 appearances in the Premier League, while he scored 17 goals and 5 assists last season in 35 appearances. He is clearly a problem at the moment, but the support and trust for him must remain despite Rashford appearing selfish.
I agree with you about the change in Rashford's performance compared to last season. There is a huge difference there. Rashford was way more a team player last season and this was reflecting onto his performance as well. However right now he has returned to being a selfish player again generally. He is having big difficulties in scoring goals too.
Actually he could have made one of his teammates score a goal against Galatasaray after that pass if Sacha Boey didn't intervene. However this is one of the rare examples of team play for Rashford I have seen in this season so far. He is a young player though so I think he would be more consistent in time.
