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.
I'm now believing in Manchester United they may succeed in defeating Barcelona. If Manchester United was able to defeat Manchester City in the premier league I don't see Barcelona to be that difficult for them. Manchester United is good to challenge any big team.
