Federer says confidence loss cost him major titles Feb 26 03:24 PM US/Eastern DUBAI, United Arab Emirates (AP) - Roger Federer says he hasn't added to his record 16 Grand Slam titles since the 2010 Australian Open because he hasn't had "confidence on my side." Now ranked third, Federer says he has had "some tough losses the past couple of years" that have denied him more major championships. He attributes this to a slight lack of confidence and not being in decline. Federer did not mention any specific matches in which that was the case. The Swiss star is in the United Arab Emirates along with top-ranked Novak Djokovic and fourth-ranked Andy Murray to play in the Dubai Championships. The tournament starts Monday.
