He said: “It was the only year I didn’t have injuries. I was so happy.”A year later he accepted that his physical state meant he could no longer play at the highest level, and he decided to sign for Al-Wakrah in Qatar on loan. It didn’t go well.He recalled: “I knew I wouldn’t have much success there. “Things went against me a lot.“I was sent off twice when I’d never been sent off before. “It must have been the frustration and it turned to anger. “I was stupid.”13-time title winner Sir Alex Ferguson became known for the ‘hairdryer’ treatment dealt out to his playersCredit: GettyAfter just 14 games in the Middle East he decided he would rather quit than accept a losing mentality, even though he could have earned a fortune at the wealthy side.Amorim said: “People said I could stay there five years and earn a lot of money, and that’s what I thought.“But when you go on the pitch I couldn’t think that way — you want to perform well.“I couldn’t stand players greeting me and chatting during the game when we were losing.”In 2017 he decided to retire from playing football at the age of 32.Four years earlier, in 2013, he had married interior designer Maria Joao Diogo in an impressive ceremony at a historic palace in the city of Coimbra.Unlike many footballing partnerships, the couple, who have sons Miguel and Manuel, do not advertise their romance on social media and prefer to keep a low profile.But Amorim did dance with Maria on the pitch when he won his first league title as manager of Sporting Lisbon in 2021.He had had some doubts about going into coaching because the demand of the job means you do not get to see much of your family.He revealed: “At first I wanted to look at doing other things because it’s not very easy for family life.“As I finished playing early, it’s a way of filling the gap. “I’ll try it. I don’t know if I’ll be good or bad.”His rise to the top has been meteoric, having started as a manager in 2018 with lowly third- division side Casa Pia in Lisbon.Amorim has been supported through his managerial career by wife Maria Joao DiogoCredit: D. RAmorim’s hot-headed nature got him into trouble the following year.During a match against Amora he put his head against that of referee Hugo Silva and was reported to have told him: “I’ll smash your face in.”Having been restrained by colleagues, he then took the dispute into the changing room, continuing to berate the ref.Amorim was banned for 90 days and fined 408 euros.According to Espresso, a Portuguese daily newspaper, he went to a psychologist for anger management sessions. Much of his success is down to a strict work ethic, which includes starting his day at 6am.And he has a reputation for looking after his players — including paying the rent for his Casa Pia central defender Deritson Lopes for a year after after he heard that the player was having to work nights at a fast food joint to support his three children.Lopes said: “He was an angel in my life.”Amorim left Casa Pia because he had been banned for coaching without the right level of qualifications and he went to Braga instead.His friend Tiago Ribeiro said: “When he went to Braga B, there were some months without work during which his assistants didn’t get paid, and he took it upon himself to make sure they weren’t lacking anything.” At Braga’s first team he won the league cup and took the unfashionable side into Europe.In 2020 Sporting Lisbon, the bitter rivals of the Benfica side he had supported as a child, paid a record fee to secure his services.It proved to be money well spent because he won the club’s first league title in 19 years.That is what Manchester United hope to be buying, having not finished top of the Premier League since 2013. He is a young coach who should be given the time to succeed, like Ferguson was.Amorim said: “I’ve grown with experience in every respect. “It’s normal to improve with experience.“I’ve made mistakes. “I’ve learnt, I keep learning.READ MORE SUN STORIES“I’ve come through difficulties, I have had great support and I’ve been lucky.”Additional reporting: VICTOR VAGOAmorim, 39, has enjoyed a meteoric rise to the topCredit: Getty More
