I think Man United's performance is slightly better than Barcelona, where in their last 7 matches Man United always won, while Barcelona had to draw 2 times and win 5 times. Man United also managed to score 17 goals and only conceded 3 goals, while Barcelona created 16 goals and conceded 9 goals. The numbers above are not a guarantee for a victory because there are indeed other factors that have a big influence on a match. But those statistics can still be considered that Man United is currently having a better trend than Barcelona, and of course, they have a chance to beat Barcelona.
Erik Ten Hag was able to make the Manchester United team even tougher, he did a pretty good job, barcelona and Manchester United need good tactics and strategies in the upcoming matches, seeing Manchester United's performance increase is quite high, I think Barcelona really need to be careful heart with Manchester United, under the tutelage of Erik Teh Hag who remains stable, I'm sure Barcelona will be overthrown by Manchester United.
Ten hag has been transforming MU to the a team that is having a very good team work. Manchester united shall have learned from so many previous matches about what's gonna be the weakness from barcelona. Manchester united shall focus to the barcelona's winger. Lewandowski can be prevented easily but it seems like that barcelona's winger has become the main key for the barcelona. It's too early to say that barcelona will overthrown MU.
You shall learn from the match barcelona against frankfurt. There would be lots of lesson that can be taken.
