Mourinho has come under-fire for leaving the Spaniard out of his side so far this season and the 25 year old was not even in the squad for yesterday’s comfortable win over Fulham.
Mata was linked with a move away from Stamford Bridge over the summer but Chelsea refused to sell despite the player being desperate for first team football with a World Cup coming up next summer.
Mourinho wants Mata to give more to the team defensively, despite the midfield man being the Blues best player last season, but the new Chelsea boss can see both Oscar and Mata playing together eventually.
“The evolution of the team is that I want Oscar and Mata to play together,” Mourinho told Sky Sports.
“I want that but for that (to happen) Juan has to adapt and to work to a certain way of play because I am not ready to change Oscar’s position.
“Oscar as a number 10 is a player that gives us creativity, but at the same time when we press up, Oscar is a runner, a player capable of pressing. We have our ideas and we stick with our ideas.
“Juan has to learn to play the way I want to play.
“He has to be more consistent, has to participate more when the team loses the ball. It’s not his fault, it’s just the consequence of the way he has played in the last years.”
