Povetkin toughest fight since Klitschko's bout - Joshua

Anthony Joshua

The unified champion weighed four pounds more than for his last title fight against Joseph Parker, tipping the scales at 17st 8lbs 5oz, with Povetkin coming in at 15st 12lbs, one stone and 10 pounds lighter.

Joshua, 28, admitted to feeling under "tons of pressure" as he returns to the scene of arguably his greatest triumph, an 11th-round stoppage of former champion Wladimir Klitschko previous year.

The last time the 28-year-old fought at the national stadium, however, he defeated Wladimir Klitschko in stunning fashion, climbing off the canvas to stop the Ukrainian in the 11th round.

"We've been away for a while, we're back now with Alexander Povetkin", Joshua told a news conference on Thursday.

Joshua, the IBF, WBA and WBO belt-holder, weighed in at 111.6 kilograms (246 pounds), slightly more than for his most recent fight against Joseph Parker in March.

In the buildup to Saturday's fight, Joshua has talked about how he trained with cruiserweights to prepare for Povetkin's smaller build.

"The one who's toughest will come out victorious".

"I'm very calm, I feel no pressure and am very happy about this fight taking place so soon".

"When I fought Klitschko, I was much weaker and in worse shape than I am now", he said.

Returning to fight at Wembley for the first time since that night, Joshua has admitted the fear of losing is always there and that he will have to be at his best to beat his opponent.

"Just signed my portion of the contract of the Wilder versus Fury fight".

"You can't beat me, I will out-heart you, I will force my will upon you until you quit and that is a promise. I've got my strength back, my body has been broken down and put back like never before", he added.

"This is not new to me, this feels like home", he said ahead of a bout that pits two former Olympic boxing champions against each other, Joshua having won gold at London 2012 and Povetkin at Athens 2004.
