In-form Federer may have five more years
Roger Federer suggested he could play on for another five years after the Swiss eased into the French Open last 16 with a straight-sets win over Damir Dzumhur.
It is the 11th consecutive year that Federer has made it past the third round at Roland Garros and the number two seed was untroubled as he won 6-4 6-3 6-2.
The 33-year-old last lifted a major trophy at Wimbledon in 2012 but he has been in good form this season and is yet to drop a set in Paris.
"Would winning a grand slam make me play longer? Possibly," Federer said.
"I may stop the following day or I may go on for another five years, I don't know.
Joining Federer in the last 16 is Swiss compatriot Stan Wawrinka, who cruised past American Steve Johnson 6-4 6-3 6-2.
Defending women's champion Maria Sharapova, who has been struggling with a cold this week, made a potentially tricky third-round encounter look easy as she beat Australia's Samantha Stosur 6-3 6-4.
Sharapova (pictured) needed three sets to beat Stosur when the pair met in last year's round of 16 but the Russian enjoyed a much simpler passage this time, winning in one hour and 40 minutes.
The victory wraps up a successful first week for the number two seed, who has reached three consecutive finals at Roland Garros and now plays Czech Lucie Safarova for a place in the quarter-finals.
Czech Safarova, who beat Germany's Sabine Lisicki 6-3 7-6 (7/2) in round three, has lost her last five matches against Sharapova.
