Chelsea midfielder Juan Mata says he's a better player for working with last season's managers.

Mata feels he's improved over the past 12 months.

"Last season I changed my position slightly and I was playing in a more central role, so that's better for me in terms of getting into the box and scoring goals.

"It was thanks to Rafa Benitez and Robbie Di Matteo because they changed things for me. I feel I've improved in terms of judging when to arrive in the box, as well as providing assists, so it's important for me to score goals," Mata told
