Roger Federer says he hasn't added to his record 16 Grand Slam titles since winning the 2010 Australian Open because he hasn't had ''confidence on my side.''
Now ranked third, Federer says he has had some tough losses over the past couple of years'' that have denied him more major titles. He says that is due to ''a bit of confidence not on my side and on my opponent's side'' rather than his form being in decline.
Federer didn't nominate any specific matches.
The Swiss star is in the United Arab Emirates along with No. 1 Novak Djokovic and fourth-ranked Andy Murray to play in the Dubai Championships, which starts Monday.
