Mata has found himself out of the starting lineup this season, despite being named as the club's player of the season last year, but the Spaniard has insisted that he is enjoying his time playing under the Portuguese coach.
The 25-year-old told The Telegraph: "To be the perfect player is very, very difficult. If you ask me last season if it was the perfect season, it was the best in my career, but I could still have done better.
"I think that Jose can help me. I think he's a manager who analyses everything, not just in our team but in the opposition.
"You can see it in the statistics, you can see it how he re-watches games every time. He's a manager who likes intensity, who likes pressure, who likes to be a compact team and I think he had success where he was."
The former Valencia playmaker has only featured in half of Chelsea's matches this season.
