Great Britain's Anthony Joshua said he was hungry and desperate to take his world heavyweight titles back from Ukrainian Oleksandr Usyk when they meet in a rematch in Jeddah, Saudi Arabia, on Aug. 20.

The pair went face-to-face with each other during a news conference in London on Wednesday ahead of the "Rage on the Red Sea" clash.

Usyk beat Joshua in front of a sellout crowd at London's Tottenham Hotspur Stadium last September to take the WBA, WBO, IBF and IBO belts.
