Nottingham Forest's attack is relatively weak. However,
I do not think that Nottingham Forest has a weak attack. They were able to score two very quick goals against Manchester United, and almost every time they have played against the big teams, they have always scored even if they do not win the game. Manchester United were fortunate to have won that game against them.
However, Manchester United conceded two goals. That's why I think Manchester United's chances of dominating against a big team like Brighton are very low. My guess is Brighton will win or the match will be a draw.
Brighton is like another version of Nottingham Forest, but unlike them, they need to feared because of how well the players play and how any of them can score. Aaron Wan-Bissaka will have to keep Kaoru Mitoma calm min the game because he can become a lot of trouble for the suffering Manchester United Defense. Diogo Dalot will have to do the same at the other side against March, and in middle Maguire will face the pressure of an experienced Danny Welbeck.
