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.
Brighton is one of the teams that is able to make it difficult for big teams to achieve maximum results and if you look at their current performance it is very consistent. They could beat Manchester United quite easily considering the many problems Erik Ten Hag is currently facing. The three Brighton players you mentioned are devastating for Manchester United's defense and especially Karou Mitoma will definitely be very difficult to stop because he has speed and good dribbling.
Brighton is a strong team that's for sure but I doubt they will be able to win against Manchester United.I think Manchester United team should have taken precautions to not lose like last year when they were devastated at home from Brighton in a big surprise in the first week of the Premier League 2022/2023 season.
This time I think Manchester have the power to beat Brighton at home or at least get a draw which I think would be not a so good result for them,they need to get the three points at home in front of their fans.We have to see what the teams have improved during this 2 weeks break from Euro qualifiers.
