Amorim has emerged as the favourite to take over at Manchester United following Erik ten Hag's sacking. His club Sporting Lisbon confirmed the English club's interest on Tuesday.
Manchester City's Pep Guardiola was asked about the Portuguese in a press conference and was full of praise for him. "All I can say is that I played against Ruben and his Sporting and their pressure was very, very good," Guardiola told reporters,
"I spoke to Matheus Nunes, who was coached by him, and he told me very good things. This season they haven't lost - or won any games - in the Portuguese League, and in the Champions League they have the same points as us.
"I have the feeling that United [also], from what I hear from him, is a good coach. Manchester United wants coaches of that level. It's not that the coaches who have been there in the last five, six, seven years weren't capable of being at Man United," he continued.
"What will happen, we don't know. What happened here with my experience doesn't mean it will happen with others, because we're talking about the coach, the club, the structure, the physiotherapists, the doctors, the players. There are many things. What happened here doesn't mean it can happen elsewhere." he concluded.
