Andy Murray hopes his split with Amelie Mauresmo isn't seen as a failure for women coaching top players.

Speaking at the Italian Open on Tuesday, Murray says "in my opinion it's nothing to do with Amelie being a woman. ... It takes a lot of time to do the job well and properly. It's not easy to do that for four, five years in a row."

Mauresmo said in a statement Monday that "dedicating enough time along with the travel has been a challenge for me."

The Frenchwoman gave birth to her first child in August and took six months off from coaching.

Murray adds that he hasn't "really thought too much about a new coach" and that he's "not worried" about his ranking after dropping to No. 3.
