This Saturday, at the o2 Arena in London, Anthony Joshua faces the American Charles Martin for his IBF heavyweight title.

The 26-year-old Joshua, who won Olympic super-heavyweight gold in London four years ago, has knocked out all 15 of his opponents so far in his professional career, but will take on a sterner challenge in Martin, who is unbeaten in his 24 fights, with 23 wins and one draw.

Martin, 29, won the title back in January, after his opponent, Vyacheslav Glazkov, was forced out of their fight in the third round after suffering a cruciate ligament injury.
