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.
You are right that Amorin needs to understand that he has now taken charge of one of the biggest clubs in the world. Manchester United are ready to spend a lot of money. However, Amorin needs to deliver the expected results. Amorin is a talented coach but not very experienced. That is why Amorin is feeling a lot of pressure after taking charge of Manchester United.
I believe that Amorin will be able to stabilize the Manchester United team. I have no doubt that he is talented. I saw Sporting's performance against Manchester City. Sporting had a very organized gameplay. Sporting performed excellently. Sporting was able to defeat a big team like City.
Manchester United's squad is not weak. There are many talented players in United's squad. Amorin needs to create a stable match strategy. Although new match strategies can be created quickly, it takes time for the players to adapt to the new strategy. So I wouldn't be surprised to see United's inconsistent performance in a few more matches.
