Current IBF super-middleweight champion James DeGale has backed Anthony Joshua to knock out heavyweight title holder Charles Martin within six rounds, in the Londoner's first title fight at the O2 this weekend.
Martin is set to be Joshua's sternest test to date, as the 26-year-old looks to maintain his 15-0-KO15 record against the American, who prematurely secured the IBF heavyweight belt against Vyacheslav Glazkov, who suffered a serious knee injury in the ring.
But while some have questioned whether it is too early for the Olympic gold medalist to challenge for a world title, fellow Londoner, DeGale, is confident that Joshua can do the job in front of a home crowd.

"Questions are going to be answered about both of them on Saturday night. But I am expecting Anthony Joshua to knock him out inside the first six rounds." DeGale told Sky Sports.
"But it's the heavyweight division, he could of course be knocked out himself.
"We know Joshua is good, but we still don't know really how good he is. I am expecting him to win though and I am looking forward to being there."
Martin feels robbed
But while DeGale is sensing the bout will swing in the favour of the Brit, Martin is eager to put on a performance to silence the home crowd - training to a chorus of boos from 1000 boxing fans in the week of the fight - after winning the IBF title due to a Glazkov injury, in January.
"I felt that I got robbed of a performance," Martin told Sky Sports. "I just wasn't satisfied with the way it ended, but it was out of my control.
"The belt is obviously in the right hands, but I'm still here to prove myself. Still feel that I've got something to prove, know I've got something to prove and I'm going to prove it on April 9."
Full of confidence
And despite the circumstances in which he won the heavyweight title at the beginning of the year, the 29-year-old is oozing with confidence ahead of Saturday.
"The word 'think' is being unsure, like I think I can do something," Martin added. "I'm going to say I know I can touch his chin, I know I can test it, I know I can knock him out. That's the confidence that I walk this earth with.
"This is my profession, this is my livelihood, this is how I feed my kids. When I step into the ring, I'm going to go to work and do what I do best. He's going to feel my presence right away."
