After the disappointing defeat by Brentford, Amorim said: "I am never concerned about my job - I am not that kind of guy."The Portuguese, 40, has been criticised for his stubbornness in sticking with his favoured 3-4-2-1 formation. Speaking on BBC Match of the Day, ex-Manchester City and England defender Micah Richards said those tactics could lead to "his undoing" and Premier League record goalscorer Alan Shearer said Amorim was fortunate to have avoided the sack."I just don't know what's going on," admitted ex-Birmingham City, Derby County and Plymouth Argyle boss Rooney, 39."I have tried my hand in management and it didn't work out too well, I get it. Ruben Amorim is my age, he is still a young manager and I'm sure he still has a massive future, but what's going on at Man Utd, this is not Man Utd."I honestly hope he can turn it round and he does. But if you're saying to me, 'do you believe he will?', then, after everything I've seen, honestly, I've got no faith in it."The former England skipper, who also captained United, added: "I don't recognise the whole football club. I don't see players fighting, I don't see character, I don't see desire to win."I go to a game watching, expecting, here we go again - expecting the team to lose or maybe pick up a point."It's not even just results on the pitch. It's everything about the club that needs fixing - Jim Ratcliffe and Ineos have walked into a real challenge. "We're seeing staff members getting sacked after 20, 30 years who are very important people to that football club. "The soul has gone from the club. It needs a new engine, a new lease of life. It needs something to kickstart that football club."Ratcliffe's Ineos Group bought a 27.7% stake in United in February 2024 worth about £1.25bn ($1.6bn). The overall number of employees has dropped from 1,100 to 700 in the past two years following controversial redundancies.The Glazer family, who have owned the 20-time English top-flight champions since 2005, retain a majority stake, but Ineos have taken control of the club's football operations.
