Mata agrees the arrival of the creative duo has helped bring his own game on to another level.
"As much as you play and understand each other, above all else it's a real pleasure for me to play alongside them both," he told Chelsea's website.
"Eden and Oscar are both young players and so talented. When I play with them I just try to assist, pass the ball and make good movements. I already feel that we understand each other really well, and hopefully it will only get better in the future."
