The midfielder credits Martinez with extraordinary powers of motivation, and he has an FA Cup winners medal - secured against the odds after a famous Wigan victory over Manchester City in May - to underline that belief.
"I think it's something the lads at Everton have noticed already even in such a short period of time, he gives you a confidence, a deep belief," says the 22-year-old.
"All the players have been speaking about it. The way he sets up is so smart, it's as if you're playing with an extra man at times.
"In the (FA Cup) final we had huge success even though everyone wrote us off beforehand. He just said go out and enjoy it. The way we were set up tactically was perfect and it worked magnificently."
