The Spanish striker, who is now at Chelsea, was handed his professional debut as a teenager by Mourinho while the two men were still at the Bernabeu, with the Portuguese manager playing a key role in his development.
However, one Mourinho pep talk got Morata a little too worked up, and he ended up wiping out Spanish teammate Diego Costa, then playing for Atletico, in the Madrid derby.
Speaking to Movistar+, Morata said of Mourinho: ‘He has character, he took care of the homegrown players.
‘He gave me the first big contract with Madrid and he told me: “If you get it right you will not have to work in your life”.
‘I did not focus from the first moment, I was 17 years old and trained to have fun, not to be a Madrid player or to have to support my family.
‘Mourinho told me I had to focus on me. He gave me the alternative. I played with Nacho in the reserves and he told us that we had to fight hard, that is what he wanted, what he likes.
‘Mourinho told the two of us that in the Calderon [against Atletico Madrid] we had to fight. I almost took out Diego Costa, I gave him a brutal kick! Sometimes I remind Costa and we laugh.’
Morata was very nearly reunited with Mourinho at Manchester United, though the Red Devils ultimately hijacked Chelsea’s move for Romelu Lukaku and signed the Belgian instead.
