He did get an offer as Jurgen Klopp replacement at Liverpool. Even so Amorim must be aware that managing Man United is a tough challenge, we will not put too much expectation until the end of the season to see real results. Amorim was only appointed as head coach which means he will focus on player development and does not have the authority to buy players. Maybe Ineos has learned from its decision to give Ten Hag the position of club manager by arbitrarily buying useless players.
Ruben Amorim will try to make the Manchester United team better in the rest of this season with the abilities he has even though the team management does not expect too much from Amorim because he has just arrived to coach a team that has been slumped by the previous coach. And I think it doesn't matter if he is not given the authority to buy new players as long as he is able to change the existing players to be better than before in the current season.
it all depends on the head coach's strategy if Amorin can do his job well then he can build this club better in the future the management hopes that his club can rise again like before.
Manchester returning back to their glory days? That all depends on work of this their new manager Amorin, though his record at sporting Lisbon has really been good but this is the English premier league, nothing is given, in other to achieve anything he has to work, and I believe that if he can be able to utilize the players at his disposal at the club right now, their season might get back on track.
I know that for the past few seasons under the leadership of Eric ten hang, Manchester united have been playing without an identity, so I believe that Amorin will have to correct that flaws, because a team as big as Manchester united shouldn't be playing as if they are playing street football where their is no playing system or identity, but the most important thing is that as he plan on building his own Manchester united team, he has to be getting the winning, because no matter how pleasant your playing system is, if you aren't winning, it wouldn't make sense to the supporters or even the hierarchy, so he needs to be getting the desired result in as much as he is trying to build, if not, he might not even last more than a year, that's the ugly reality of today's football, because it's now a business that must be in good shape regardless of if it's in a building stage or not.
