KEY POINTS:
NEW YORK - World tennis No 1 Roger Federer has dismissed suggestions his career is in decline and said he would use his recent defeats as motivation after recovering from an early-season virus.
The Swiss player was beaten in the first round in Dubai last week by Briton
Andy Murray, his first match since losing to eventual champion Novak Djokovic in the Australian Open semifinals in January.
"In Switzerland there is a little too much speculation my career is over," the 26-year-old Federer said ahead of Monday's exhibition match against former No 1 Pete Sampras at Madison Square Garden here.
"People just need to know I'm healthy and happy and not miserable and down and out."
The 12-times grand slam singles champion, who competes at the Pacific Life Open at Indian Wells, California later this week, was told he had mononucleosis (glandular fever) after the Australian Open.
"Honestly, losses like this motivate me more than anything," Federer said.
"Trying to come back, trying to prove I'm still the one to beat.
"I just want to show I can do it over and over again."
The back-to-back defeats dented Federer's aura of invulnerability and fed the confidence of those younger rivals who have seen him reign as No 1 for a record 215 consecutive weeks.
Within two grand slam titles of Sampras' record haul of 14, Federer said his affection for tennis was greater than ever.
"I love competing on centre courts all over the world. So many people are happy when I get there. It touches me. I love to practice more and more now," he said.
"What I enjoy most are the matches, the pressure, the fans, centre court. I hope that's going to stay with me as long as possible."
Federer said he was looking forward to competing at the Beijing Olympics in August and to more Games campaigns beyond.
"The (London) Olympic Games in 2012 is something I'm looking forward to, and go from there. See how I feel with my fitness, my motivation."
Federer may have made his worst start to a season in eight years but Sampras was confident the Swiss would soon be winning again.
"In a lot of ways Roger has created this sort of monster of being unbeatable," said the 36-year-old American.
"If you lose a match here, lose a match there, people have the assumption he has lost his edge, lost his dominance. I don't look at it like that at all.
"He'll play Indian Wells and he'll play Miami (in two weeks) and do fine at those events. When it comes down to it at the big, big events, I think he'll be the guy standing with the trophy."
