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.
