Roger Federer "relaxed" after cruising through to French Open fourth round

Roger Federer has admitted that he feels "relaxed" after easing his way into the fourth round of the French Open.

The 17-time Grand Slam champion sealed a 6-4 6-3 6-2 victory over Damir Dzumhur in Paris this afternoon.

"I'm quite relaxed," Federer said on the court. "I didn't know him and I didn't know how he'd play on the key points."

Federer last won the tournament back in 2009.
