I keep hearing Manchester United were lucky. What do you even mean? Sit seems you guys have written off Manchester United completely. Have you forgotten it was this same Manchester United that eliminated Arsenal from the FA Cup? I think Manchester United played well, although they didn't win but the way their performance was good. I believe if Manchester United had a proven striker in their squad, they could have won Arsenal. Anyways kudos to Ruben Amorim and his boys I just hope they can be able to build on this momentum and be able to perform on this same intensity consistently.
In that game, if Man UTD didn't take all three points from the game is because of the last minute save Raya made to keep Bruno Fernandes shot from giving the hosts the win. I won't say the Red Devils were lucky, if anything, they matched Arsenal's aggression equally. They gave as good as they got and even when Arsenal should have buried some of their chances, the no.1 between the sticks, Onana was always there to make Arteta's men more frustrated.
Arsenal are just what you'd call a team competing in the EPL and not aiming for anything else because if they were, they would not have allowed Liverpool to have that much point gaps over them.
Manchester United can eliminate Arsenal with a good game or win a very good game against another team. It may not be right to attribute this situation to luck, but the real problem is that Manchester United's performance is not consistent. There may be a squad at a level that can win against any team, but it is the same squad that loses points very simply. The problem with the team is that they cannot show their good performances consistently.
Actually, Arsenal has a similar problem because they play very good football at the beginning of the season but they cannot show the performance they want towards the end of the season. I think teams should do something to solve this imbalance in their performance.
