Fernando Gonzalez will begin working with Darren Cahill on a part-time basis.

"I will begin to work with Australian Darren Cahill, a coach that got a lot of results with Agassi and Hewitt at their best moments and in different years," said Gonzalez on his website. "It won’t be full time because of his obligations but I trust he will help my aggresive tennis with the best tactical moves of the Australian school."

Cahill is a coach with the player development program at adidas, which sponsors Gonzalez. Gonzalez was previously working with Martin Rodriguez.
