A jury has seen film of Premier League footballer Anton Ferdinand allegedly hitting a man outside a nightclub.
Anton Ferdinand claims he acted in self-defence
The prosecution claims CCTV footage shows the West Ham defender in a brawl outside Faces in Ilford, east London, in October 2006.
Mr Ferdinand, 22, denies charges of assault occasioning actual bodily harm and affray, at Snaresbrook Crown Court.
His co-accused Edward Dawkins, 28, of Beckton, east London, also denies similar charges.
Mr Ferdinand says he acted in self-defence, fearing he would be robbed of a £64,000 watch.
Prosecutor Alex Agbamu said alleged victim Emile Walker was assaulted by a group of men including the co-defendants.
He told the jury they had to decide whether the pair had acted in self-defence using reasonable force during the fight.
He alleged the fight broke out after Mr Ferdinand's cousin, who has not been charged, struck Mr Walker.
However, Mr Ferdinand claimed he was himself attacked outside the club and feared his watch would be stolen.
He alleged one of a group of men began kicking him and he was punched with enough force to loosen one of his teeth.
Mr Ferdinand's brother, Rio, the England and Manchester United footballer, was among those in the courtroom.
The trial continues.
