Roger Federer is turning his back on the Swiss.

CBSSports.com is reporting that the No. 2 men's tennis player in the world will forego Davis Cup play for Switzerland in 2015 after helping his country win the title in 2014.

And it appears that Federer isn't losing any sleep over his announcement, either.

"It wasn't a difficult decision," Federer said Monday at the Dubai tournament. "I have played for so long, and I think by winning it I can finally do whatever I please, to be quite honest."

The 33-year-old Federer pulled no punches in explaining his decision to The Associated Press.

''It's been a big burden for me throughout my career and one of the things that have caused more difficulties in my life than many other things, I must say,'' Federer said.

''I always feel there is so much guilt put on you from the federation or from the ITF more so than anybody else. So I'm happy I was able to finally tick that off and do it altogether.''

And the only reason he did it last year, he said, was to help his countrymen take home that title.

''I totally did it for the boys more than for me, to be quite honest,'' he said. ''I just really wanted Michael (Lammer) and Marco (Chiudinelli) and Stan to get it because they deserve it. So for me, this year, it was very clear that I was not going to play.''

After a bounce-back 2014 in which Federer climbed from No. 8 to No. 2 in the world rankings, he spent what would have been his offseason at the end of the year competing in the Davis Cup Finals, followed by a world team tennis tour in India.

Federer subsequently loss to Andreas Seppi, a player he had defeated 10 consecutive times, in the third round of the Australian Open. Before that loss, Federer had advanced to the semifinals in Melbourne in 11 straight years?
