Jesus was the coach at Vitoria Setubal, Ferreira's club in Portugal prior to his move to Porto and the multiple trophies that followed.
"He was an important person at the beginning of my professional career," Ferreira told chelseafc.com.
"He was the one that taught me all the tactical things as a right-back because it was when he went to Setubal that I returned from the national team having played right-back for the first time.
"I played a game away in Holland as a right-back because the usual right-back for the national team had got a second yellow card in the game before, and he had to miss the game. The national manager talked to me and asked me if I could help by playing in that position.
"I was happy to help," he continues. "To play for the national team was something really important for me. We ended up getting a good result - we drew 1-1 - and when I got back from the national team was when we changed manager at Setubal.
"So in my first session with Jorge Jesus, he just started me as a right-back. He had watched that game and he liked me there, so I was a right-back."
