The Croatian ranks second in the league for what Opta call 'ball carries': a player moving the ball five metres or more.
"My game is to open spaces for other people," Kovacic told chelseafc.com.
"It's a big strength and I have felt I am trying it a lot more because we play a little bit different football to last year. Now we are more direct, more aggressive, we just try things we didn't try last year. I feel better.
"I think my best position is in a midfield two," he adds.
"I can play as well in a midfield three, but in the two I feel maybe more comfortable with more freedom. But in the end the formation doesn't matter too much."
