The 39-year-old sat down in front of the media at Carrington on Friday, two days out from his maiden Premier League game, which comes on Sunday when the Reds travel to Portman Road to face Ipswich Town (16:30 GMT).
Journalists present were keen to ask Amorim about his relationship with his compatriot, Mourinho, who welcomed him to Carrington on an internship in 2018, when Amorim was still studying to become a coach.
Ruben explained that Jose had sent him some thoughts soon after his switch from Sporting to United, and went on to speak about the broader influence Mourinho has had on his career – plus the differences between the pair.
