The owners ( @INEOS ) has also said they'll most likely see him as the head manager for a long period of time. That's some good news to read and hear but they are pretty good at talking than doing, let's see what happens finally. I want to see them help him get the players that can suit his style of play and also fight for the Manchester United badge. Manchester United fans can be toxic same time without patience. I will not raise or high my hope next season, it'll take some 2-3 years.
It most likely Amorim will stay as per Sir Jim's statement. The problem is his club is almost running out of cash. They have to balanced it again as almost all of their cash drained by Glazer family.
Amorim obviously has to sell a lot of players in summer in order to rebuild the squad. I don't think they can do that without selling players first.
Amorim has to find demand for his players who listed on the list of players to be sold.
