Ahead of next week's ATP World Tour Finals in London, those taking part including Andy Murray and Novak Djokovic will etch their signatures onto a bottle of methuselah that is expected to raise up to £20,000 at auction.

The auction of the golden Moët & Chandon methuselah will take place at the Royal Courts of Justice on Saturday night in support of the Great Ormond Street Hospital Children's Charity. The world's top eight players, including Roger Federer and David Ferrer will be in attendance at the event.

Emelie De Vitis, Marketing Manager, Moët & Chandon UK said: "The Barclays ATP World Tour Finals Gala is the only night of the year when the world's top eight step out in black tie for one charity. As the official Champagne of the Finals, we're delighted to be able to support, and hope guests dig deep on the night to raise money for such a good cause."

The ATP World Tour Finals begin on Monday where Djokovic and Murray will be hoping to make amends after the pair made early exits from the Paris Masters this week.
