This incredible sporting occasion is the final tournament in the ATP calendar and features the top eight men’s singles and doubles players in the world, including Novak Djokovic, Roger Federer and US Open champion Marin Cilic.

We have 29 pairs of tickets to give away in total for this end of season finale, including both semi-finals and the final.

This year Barclays are saying thank you to those who represent the true spirit of the game, just like the 2014 Barclays Ball Kids squad who will be taking to the court at The O2 alongside their tennis heroes and demonstrating their skills of endurance, co-ordination, balance, speed, ball-skills, teamwork and leadership.

For your chance to win a pair of tickets simply tell us, in less than 150 words, about a time when you have done something that represents the true spirit of the game.

It could be a time when you have shown exemplary sportsmanship, or fought back from being match point down, or helped out a fellow player. We would love to hear your stories.
