Roger Federer surprised even himself with how well he played in the 2006 season, which he rounded off in some style by winning the Masters Cup on Sunday.
The 25-year-old's dominance of men's tennis is such that the Swiss could extend his holiday into March and would still break Jimmy Connors's record of 160 consecutive weeks as world number one on February 26.
"I think that is definitely one of the big records I've broken, maybe the biggest so far in my career," Federer said.
"I'm waiting for that date to come along and then I'll celebrate it, not right now."
The 25-year-old thrashed American James Blake 6-0 6-3 6-4 on Sunday in his last competitive game of 2006 to win his 12th title of the year, a feat no player has achieved since Thomas Muster in 1995. "To come to this point in my career where I feel so happy with my game, it's come such a long way that I am out of words really to describe this performance," he said.
