Jack Waller
Jack Waller is a centre forward for the Team GB water polo team as they prepare for the London Olympics.
He began playing the sport when he was aged 11 and came from a very sporting family - his sister swam internationally and his father also played water polo.
Waller made his Great Britain debut in 2007 and played a vital part as the British junior team qualified for the 2008 European Championships, finishing 13th.
The 22-year-old water polo player was part of the British team who finished fourth at the European B Championships in 2009.
In 2010, he joined German side SV Wieden but this season he has been playing for CN Sant Andreu in Barcelona.
Astonishingly, in 2011 he broke his leg in three places yet is now ready to perform in front of a home crowd in London this summer.
