Inter Milan legend Marco Materazzi has been in touch with Chelsea boss Jose Mourinho since his move to India.
The World Cup winner is now player-manager of Indian Super League side Chennaiyin.
"Mourinho sent me compliments after my first win, but I didn't need to speak to him. I keep his teachings within me," said Matrix.
"My assistant manager walks around with Mourinho's book under his arm and teaches the team the same training methods he made us do at Inter."
