Oleksandr Usyk believes the heavyweight title fight against Joshua will be won with brain rather than brawn.
The 34-year-old will fight Joshua for the IBF, WBA and WBO title at Tottenham Hotspur Stadium.
Usyk says the one with more patience to go through all the pressure in the fight will be victorious.
The Ukrainian boxer is aiming to be the third fighter to become both a cruiserweight and a heavyweight world champion.
He is undefeated since winning Olympic gold alongside Joshua in London in 2012.
At the scales, Joshua weighed in at 109kg while his Usyk weighed in at 100kg.
The fight program begins at 9am tomorrow.
