They have every right to feel that way but they need to give Amorim some break. He is just starting the team and he is the only person that see what we the fans are not seeing. Not only that, yiu also need to consider that there is much demanded which he is not even an excuse but he will get better with time. I know Ruud had a great 3 weeks with the boys but I he isn't the man that was assigned as permanent coach, he just need time to do what everyone is asking or him.
The only think of Manchester United is that they gave so much time for Erik to waste their time and now they are they are trying to even get above top and even the minor ad moving gradually on the table. If Ruben Amorim do what is necessary for him to get the club in a better place, I have some confidence in their success because he brought some assistant coach to him, this is how he manage his games in sporting, similar wlll be done here.
I know that most of their fans are now comparing him to rud van nistelrooy, in my own opinion that's not a good idea, because rud van nistelrooy knows the club and the player more better than him, so he needs time to know the quality of his players, so that he can establish a playing system that best suit them, so time is very much essential, and that what he needs.
