This match against Ipswich was the perfect match he should have used to announce himself in the premier league by scoring lots of goals and not going to drop point. This game was like a lost and not a draw. Manchester United scored very early in the match and it gave lost of fans hope that they have found a manager that can make them play better but they couldn't score again and let in an equalizer. Amorin is already feeling the pressure of the premier league as he has said he hasn't faced the amount of press that he has faced in just few days of being in the premier league when compared to all his stay at sporting. He needs to realize that he's in a big club now and not a small club.
I don't totally agree with you. While the match between Ipswich and Manchester United was a good platform for Ruben Amorim to announce himself, that doesn't mean his approach in the game lacks merit. I think Amorim already announced himself to the Premier League when he defeated Manchester City. Amorim is new to the league, and it's natural for any manager in his position to take time to evaluate his squad. While fans and critics may demand immediate result, Amorim will be looking at the long term plan which involves establishing the right mentality and identifying the right set of players that will follow him to the next level.
