Mata will wait until he meets the Portuguese before judging the stories.
"Nobody at Chelsea has told me that Mourinho wants me out," he told Marca.
"When I finished the season I was told that they were very happy with my performances and with the two years I've spent with the club.
"I have three years left on my contract. I'm very happy with Chelsea.
"Mourinho? I'd prefer to wait until I meet him and work with him before I judge him. That's simple logic."
