Names of the eight players set for the showpiece end-of-season tennis tournament at The O2 , Greenwich, have been locked in.

David Ferrer and Kei Nishikori booked their tickets to Greenwich following the Swiss Indoors tournament, completing the line-up for the Barclays ATP World Tour Finals from November 15-22.

They join a mouth-watering bill of Brit Andy Murray, three-time defending champion and 2008 winner Novak Djokovic, six-time former winner Roger Federer, Stan Wawrinka, Tomas Berdych and crowd favourite Rafael Nadal.

Nishikori made history last year as the first Asian player to qualify for the season finale in singles. On his debut, the Japanese star beat Murray and Ferrer to reach the semi-finals, where he fell to Djokovic.

He said: “I am very excited to go back to London. This tournament is one of the flagship tournaments of the year for us and I look forward to coming back.”

Ferrer will make his seventh appearance at the season finale. The 33-year-old Spaniard reached the final on his debut in 2007 in Shanghai and qualified four years in a row from 2010-13.

He said: “It’s an honour to be back in London and be amongst the best players in the world once again. It’s been a great season for me and I really look forward to the tournament.”

The tournament uses a round-robin format, players will compete in a minimum of three matches each during the group stages as they battle for a berth in the knockout semi-finals.

Each session will include one world-class doubles match, which sets the stage for a singles clash. The semi finals and finals are on Saturday and Sunday, November 21 and 22.
