Manchester United team is performing very well. Last season there were some great problems within the team. However, at the beginning of this season, the team has prepared itself brilliantly.
I don't understand your observations and why you said that Manchester United is playing very well, but to me, as a big club in England and the world playing in this type of form, I will not say that Manchester United is playing well. If Manchester United loses two and wins two games out of the four games they have played,especially loses to its competitors Tottenham and Arsenal, and struggles to win the two games against Wolves and Nottingham Forest, this is to say that Manchester United is not performing well because it is not up to the club standards. Manchester United is a club that needs to fight for the Premier League title and the Champions League, not a club that needs to be fighting for the top four.
and in week 5 Manchester United will host Brighton, and this will be a tough job for Erik Ten Hag because Brighton is not an easy opponent considering their game is quite good, especially in counter attacks and they are also in 6th position in the standings.
Brighton is currently in terrific shape, and they always give Manchester United a tough time when they face them, thus Manchester United facing Brighton will undoubtedly not be an easy game for Manchester United. However, given that Manchester United is playing at home, perhaps they will be resilient and find a way to win the game. However, given their current form, I can't say that Manchester United can win the game against Brighton, who have won three of their first four games this season.
