Premier League stars were out in force to witness the tennis ATP World Tour Finals at the O2 Arena in London yesterday.

While plenty of spectators turned up to watch Novak Djokovic secure victory over former world number one Roger Federer, some noticeable faces were also in the crowd.

Arsenal duo Mathieu Flamini and Alex Oxlade-Chamberlain watched the on-court action, while Chelsea's Michael Essien was spotted sitting next to snooker star Ronnie O'Sullivan.

This afternoon's action at the O2 consists of matches between Rafael Nadal and Stanislas Wawrinka, and David Ferrer against Tomas Berdych.
