I agree with you that Manchester United's victory yesterday did not mean anything or we can call it luck. Based on statistics, Manchester United can dominate the match but many opportunities are passed in vain. Tomorrow they will fight Brighton and we know Brighton is not an easy opponent this means we can't expect Manchester United to get 3 points even a draw is a good result, IMO. Special attention to the Manchester United defense line that has conceded many goals and maybe it became their worst record.
They play at home which possibly will be got full support from fans, and will got full motivation to win the match also. I admit Brighton is not a team that can be taken lightly, MU must hard work to revenge their lost on previous session. MU on positive tren, They able to hold Liverpool, and win when meet Arsenal. The last match is show that MU on best performance even the squad is still lack of coordination. I don't know how performance Amad for this time, He is a wonder kid which possible will be guarded closely by Brigton defender. MU must improve the strategy to allowing him to move more freely in front.
