Anthony Joshua is prioritising beating Otto Wallin over everything else ahead of Saturday's bout in Riyadh.

A victory could set up a long-awaited fight against Deontay Wilder, who takes on Joseph Parker in the co-main event.

But Joshua wants to focus on his performance rather than the "glitz and glamour".

He said: "I'm here to fight.

"Of course I'm tense because I want to perform, I want to win. I've got that urge to win and I want to hurt my opponent as well.

"I'm not here to party and get caught up in the glitz and glamour."

Joshua's demeanour has been a point of interest in the build-up to the Wallin showdown.

But while the former world champion insists the absence of his usual bravado is purely down to concentration, his confident opponent is not so sure.

Wallin said: "From what I see, he seems very stiff and tense. 

"Maybe he's fed up with all this stuff.

"It won't be an upset [if I win]. Stop calling it an upset."

Organisers will hope Joshua and Wilder both survive banana skins with the prospect of a head-to-head battle between the pair potentially to follow should they both win.

The American recently claimed Joshua does not have "the heart" to face him although there have also been signs of mutual respect between the pair.

He told the BBC: "I don't want to say he's 100% afraid, but I think he's 75%.

"We'll see what happens. The future is bright and we are further [in talks] than we’ve ever been in history. I can say that with certainty. 

"Money hasn't been the issue. It comes with [Joshua] not having the heart, the will, the courage to step in the ring."
