Tennis star Peter Norfolk will have two missions in Beijing - retain his singles title and win doubles gold with Paralympic debutant Jamie Burdekin.
The 47-year-old, who suffered a motorbike accident when he was 19 that left him paraplegic, competes in the quad division for players who have a disability in three or more limbs and he plays with his racket taped to his hand.
He created history in Athens when he became Britain's first-ever Paralympic tennis medallist and comes to the Games as world number two behind American David Wagner, who he beat for gold four years ago and who will be his closest rival in Beijing.
Norfolk has won 13 Super Series (Grand Slam equivalent) titles over his career with the latest coming in July when he beat Wagner to claim his fourth British Open singles title.
As well as a number of sporting honours, his success in Athens saw him asked to perform the coin toss ahead of the 2005 Wimbledon singles final.
