Roger Federer has insisted that he has no plans to retire from tennis any time soon despite suffering his worst season to date in 2013.
The Swiss failed to win any Grand Slam titles and was on the wrong end of a number of shock defeats, before finishing the year by losing to world number one Rafael Nadal in the last four of the ATP World Tour Finals at The O2.
Despite his disappointing campaign, Federer says that tennis is in his DNA and has pledged to continue for as long as he can.
"For me, it's pretty simple: this is what I used to do as a little boy. It's something that always is there in your DNA," Federer told reporters.
"Clearly today it's different than when I was 12 years old, but it's just something I enjoy doing.
"The thing is that when you stop, you're still so young, why stop so early? Why just walk away from it because I have many other things to do in my life than play tennis? But because I can still choose, I pick to play."
Federer's last Grand Slam title came at Wimbledon in 2012.
