Anthony Joshua wants to fight until he is 36 as he gets set for the latest defence of his heavyweight titles.

The 31-year-old faces Oleksandr Usyk on Saturday night at Tottenham Hotspur Stadium and has cut a relaxed figure in the build-up to the bout.

Joshua signed a “career-long” contract with Matchroom before the contest and has revealed when he plans to hang up his gloves.

“I think 36 is a good age (to retire),” Joshua told the 5 Live Boxing podcast.

“I’ve got to put a bit of a limit (on it). I was watching the Larry Holmes fight with (Trevor) Berbick. It’s mad in boxing.

“Cleveland Williams, Sonny Liston, Berbick, they’re all just known as the guy who got knocked out by Mike Tyson or the guy who got knocked out by [Muhammad] Ali.

“Berbick was a serious fighter in his day. I was watching the build-up and they said that Larry Holmes was thinking of retiring at 31. I was like ‘what?’ I think for me 37, 36…36 is going on 37.”

Joshua, who holds the WBA (Super), WBO, IBF and IBO titles, says he thinks he will be “at peace” once he finishes.

Usyk is the 10th opponent Joshua has faced in a world title fight, having twice fought Andy Ruiz Jr.
