LONDON: Roger Federer can win a record 15th Grand Slam title on Sunday, and reclaim the world number one spot, but he insisted on Saturday that his hunger for the sport and its silverware remains undiminished.

The world number two will pass Pete Sampras's mark of 14 majors, and capture a sixth Wimbledon title, with victory over America's Andy Roddick in the final.

But there's no sign of him tiring of life at the top.

"I don't have any worries about motivation. I love this game and I want to stick around for a long time," said Federer, whose wife Mirka is expecting their first child later in the summer.

"I want our child to see me play. I want to play in the 2012 Olympics because the tennis tournament is at Wimbledon. That's something I want to be part of.

"My motiavtion won't change a lot."
