(REUTERS) - Tennis' world No. 3 Roger Federer withdrew on Monday (Oct 28) from this week's Paris Masters, as he fine tunes his schedule heading into the season-ending ATP Finals.

The 38-year-old Swiss legend lifted a record-extending 10th Swiss Indoors championship title in his home town of Basel on Sunday and has decided not to play back-to-back weeks at this stage of the season.

"I am extremely disappointed to have to pull out of the Paris Masters," Federer said in a statement.

"I have to pace myself since I want to play as long as possible on the ATP Tour. I am sorry for my French fans who I will see next year at Roland Garros."

Federer, Novak Djokovic, Rafael Nadal, Daniil Medvedev, Dominic Thiem and Stefanos Tsitsipas have booked their places for next month's ATP Finals, with the Paris Masters set to determine who clinches the final two spots for the London tournament.

Defending champion Alexander Zverev and Matteo Berrettini are seventh and eighth respectively in the Race to London.
