(Reuters) World number two Novak Djokovic said he lost motivation after winning the French Open to complete a career grand slam last year, but now feels he is on the right path to rediscover his "mojo".
The Serb, who split with his coaching team earlier this month, reached the semi-finals of the Madrid Open last week, where he lost to eventual champion Rafael Nadal.
"If I could describe my tennis in one word, I feel like I'm in transition," Djokovic said in an interview posted on the ATP website.
"After winning Roland Garros, I didn't know how I was going to feel. I never had that issue after winning a big trophy, of bouncing back and finding new ways to motivate and inspire myself.
"But last year I found some emptiness for the first time in my life in terms of motivation. I needed a few months to think about things and get that mojo back on the court."
