Joshua: Amateur days are behind me now
Anthony Joshua is fully focussed ahead of his fourth fight as a professional, when he takes on Dorian Darch at London's ExCel Arena on December 14.
Joshua was due to fight on the undercard of Carl Froch's controversial win over George Groves, but was forced to withdraw after suffering a bicep injury.

Now the British heavyweight will return to the scene of his Olympic super-heavyweight gold medal win in order to fight Darch - but the 24-year-old is adamant he has left his amateur days behind.
"I'm at the start of a fresh new chapter. The Olympics was amazing but it's in the past," Joshua told Sky Sports. "I am loving life in the pro ranks and learning every day.
"Dorian is a tough test for just my fourth fight and he'll want to make a name for himself, as all my opponents do. I am grounded, I am focused and I am taking every fight very seriously.
"It's vital that I keep winning and keep learning because one lapse of concentration in the ring could be disastrous."
Joshua has enjoyed a strong start to his professional career, winning all three of his fights to date by technical knockout. He saw off Emanuele Leo in the first round on his debut before going on to enjoy triumphs over Paul Butlin and Hrvoje Kisicek.
