Li Na has admitted that she is benefiting from her new coaching setup, both on and off the court.
The world number nine had previously been coached by her husband Jiang Shan.
However, having found it difficult to dedicate enough time to their relationship, the pair decided to hire Carlos Rodriguez to coach Li on a trial basis.
Having had time to work with Rodriguez, Li has expressed her happiness at the way it has been going.
"It's good for both me and my husband," Li told reporters. "After Carlos comes, now husband is husband. It's too tough for my mind.
"Sometimes we are training so hard on court and I'm thinking, 'You are my husband, why are you training me so hard?' It's tough to find a balance.' He did a good job, it's just not good way for the wife."
Li is currently competing at the US Open in New York.
