There have been plenty of external observers saying 40-year-old Amorim will not succeed at United, criticising him for refusing to change his 3-4-2-1 system.Ratcliffe says he is not interested in such talk and feels it comes from a position of ignorance."The press, sometimes I don't understand," he said."They want overnight success. They think it's a light switch. You know, you flick a switch and it's all going to be roses tomorrow."You can't run a club like Manchester United on knee-jerk reactions to some journalist who goes off on one every week."Ratcliffe, who owns just under 30% of United, controls all the major football decisions, even though the Glazer family retain a majority stake in the club.The Ineos owner acknowledges the Glazers, who took control of United courtesy of a leveraged buyout in 2005, get "a bad rap". He insists they are "passionate" about the club and, when asked if they might order him to sack Amorim, said: "That's not going to happen."Last month, United announced they had cut losses from £113.2m to £33m for the year to June 2025. This followed two rounds of redundancies, during which more than 400 people lost their jobs, including many long-term staff members. Scouting is among the areas where numbers have been slashed.Ratcliffe has been criticised for the job losses and also scrapping long-standing perks such as free lunches for staff."The costs were just too high," he said. "There are some fantastic people at Manchester United but there was also a level of mediocrity and it had become bloated. "I got a lot of flak for the free lunches, but no-one's ever given me a free lunch."There are two halves to a football team - there is the business side and the sports side. The biggest correlation, like it or not, between results and any external factor, is profitability. The more cash you have got, the better squad you can build."If you look at our results for last year we have the highest revenues ever. Profitability, the second highest ever. Those numbers will get better. "Manchester United will become the most profitable football club in the world, in my view, and from that will stem, I hope, a long-term, sustainable, high level of football."
