It is a fairly balanced opponent for both teams this weekend, but I just hope Manchester United does not make many mistakes or blunders that can harm themselves. Because Brighton is a fairly strong team and has also made surprises at their opponent's home, so Manchester United must really do their best to be able to win again at home when hosting Brighton.
Manchester United will make many blunders, take a look with the defending line, there are Martinez, De Ligt, and Yoro, they're bad defenders. Also you know, Onana is not consistent, sometime he play good, sometime he play like the worst goalkeeper.
The problem Brighton currently have is many players are injured, but I'm sure the results are either draw or Brighton win, I'm convinced Brighton will win.
I don't think because Manchester United have improved themselves and if you see Manchester United drew the match against Liverpool even though Liverpool are very strong against Manchester United but still they couldn't win the match against Manchester United. Brighton's record is even worse than Manchester United's so I can imagine that Manchester United will win this match easily as they have improved their defense and players' hard work. Manchester United are working hard on themselves but they are not that strong right now but it will take them some time if they keep playing well it won't take them that long they will be strong soon and their will revert to previous performance. Your thinking is a draw because of injuries but I don't understand the concept of Brighton winning because Manchester United is much better than Brighton so Manchester United will win this match.
