Mata struck twice in victory at Tottenham on Saturday.
"The three behind the striker always try to play with movement, swapping positions and trying to assist our striker," said Mata.
"That is what we did against Tottenham. We have to work in training, but we have players who play like this naturally as well.
"The three of us play more or less the same way and I'm really enjoying it.
"I don't think it is a surprise. I knew Oscar, Hazard and Fernando (Torres) - the players who play here are top players.
"I think we are playing more with the ball and in a more enjoyable way for me and for the team."
