Journalist Stuart Appleby interviews 17-time Grand Slam champion and tennis legend Roger Federer ahead of the 2012 Barclays ATP Tour World Finals in London.

The 31-year-old Swiss maestro, who has won the season-ending championships on a record six occasions, is gunning for his third straight title at the O2 Arena.

Having won a record-equalling seventh Wimbledon title this year and secured an Olympic singles silver medal at the All England Club, Federer rewrote the history books once more in 2012.

These two stand-out moments also helped the veteran assume the position of world number one again and break another record, this time for the most amount of weeks at the summit of the men’s game in the Open Era – 302.

“I’m feeling pretty good about playing again,” said Federer, who skipped the Paris Masters tournament, of which he was defending champion, to rest up before returning to the English capital.

He added: “I’m feeling confident again, it’s more about hitting the ball, getting used to the conditions, how fast it is again and remind yourself how it was last year and get inspiration from that.”

ATP tennis stars came together on Saturday November 3rd 2012 at the official Barclays ATP World Tour Finals Gala, at The Royal Courts of Justice in London, to raise more than £400,000 for Great Ormond Street Hospital Children’s Charity.
