Mata has again been a key player for the Blues this season.
He said: "Last season was busy as well but this season has been so busy. But I really like to play every three or four days and I think my body is used to playing this much.
"We also have a very big squad to rotate and we do that. To have played 46 games is a good number for me so far but I would like to play as much as I can.
"I have to be happy with these numbers and with this contribution to the team's goals and assists. But as I always say I want more because I am trying to help my team.
"My main aim every season is just to improve and to grow as a player, so let's see at the end of the season how the numbers look. So far, I am happy with my performance."
