With every defeat there are questions raised as to whether Roger Federer is losing his aura of invincibility.

But despite crashing out of the Indian Wells Masters after going down to gutsy Cypriot Marcos Baghdatis, the world No.1 is not too concerned.

Federer, playing his first tournament since winning the Australian Open in January, having pulled out of last month’s Dubai Tennis Championships with a lung infection, went down 5-7, 7-5, 7-6 (7/4) to Baghdatis, after squandering three match points in the second set.

But the 16-time Grand Slam champion said: “I think it wasn’t the worst match.

I did many good things tonight but also many bad things. It’s just a question of not letting that happen too often.

“I just couldn’t find the way to win. I was maybe one shot away. That’s how much it takes sometimes from winning or losing.

“I think as the tournament would have gone forward I would have found my groove more and more, and who knows what would have happened?

“Maybe I was going for too much, maybe playing too passively. That’s not something you can really work on. That comes through playing matches, and that’s what I need.”

And with the French Open, where Federer will be defending for the first time, not taking place until May, the Swiss maestro is still in relaxed mood.

“I will definitely play a lot of practice sets, that’s for sure, until then,” he said, with next week’s Miami Masters Federer’s next event.

“The season is long. There’s no need to panic here.”

Baghdatis meanwhile, was getting carried away with the victory, calling it the “biggest of his career”.

“A lot of emotions are going through right now,” said the 2008 Australian Open finalist.

“I lost a lot of matches against those top guys, and, you know, it’s a relief to win a match like that. It’s a great moment for me.”

Elsewhere, and Andy Roddick is feeling confident after beating Dutchman Thiemo De Bakker 6-3, 6-4 to make the last 16.

“I felt pretty good. I felt like the points he was winning he was either having to play a pretty high risk shot,” said the big-hitting American.
