Stefan Edberg, who recently spent a week hitting and consulting with Roger Federer, says he is open to furthering the relationship and could wind up coaching the 17-time Grand Slam champion—if an agreeable schedule can be worked out.

"It's a matter for us to find time to fit it in," Edberg told Stockholm's *Svenska Dagbladets*. “If we can, I would be more than happy. The idea of the [training] camp was that I would give my views and come up with some feedback. He wants to try some new things.”

Edberg said he advised the Swiss to play a more attacking game. Federer failed to beat any of the younger members of the Big 4 in 2013.

"I was very surprised (that Federer asked) because it's so long since I left tennis," Edberg said. "But I was also very flattered. I've never really thought about coaching and if it had not been Federer doing the asking, honestly, I would not have been interested."
