Former world champion and Sky Sports expert analyst Carl Froch is hoping that WBC heavyweight champion Deontay Wilder scores a crushing knockout over Luis Ortiz.

Wilder will defend his belt against Ortiz on Saturday night from the Barclays Center in Brooklyn, New York.

Ortiz (28-0, 24 KOs), who is regarded as a dangerous puncher with a very hard punch, is widely viewed as the toughest opponent of Wilder's career.

Froch pushing hard for Wilder - because the Nottingham star would like to see him unify with WBA, IBO, IBF champion Anthony Joshua (20-0, 20 KOs) by the end of the year.

He believes a destructive knockout over Ortiz will place a lot of pressure on Joshua to make their fight happen by the end of this year.

"Deontay Wilder needs to do a proper job on Luis Ortiz. If he does, Anthony Joshua will be sat there sweating a bit. Wilder should and I hope he does. I am not an Ortiz fan because of what he has done in the past, and you know I am a big 'AJ' fan. Of course, I want Joshua to go on and become the undisputed heavyweight champion of the world, but I am also 'just' a boxing fan," Froch told Sky Sports.

"We want to see the very best beat the very best, if they want to get to the very top, and I know Joshua does. If Wilder's power explodes, and he blows Ortiz away, that and his whopping ego will suddenly put a bit of pressure on."

Joshua is back on March 31, in a unification showdown with WBO champion Joseph Parker in Cardiff. If Wilder wins on Saturday, he plans to be ringside to call out the winner.

Joshua's biggest win to date, is a TKO of former division ruler Wladimir Klitschko from last April.

But even Froch admits that Klitschko, who at that time was 41, was way beyond his best. He was also coming off a loss to Tyson Fury and a career long stint of inactivity. Klitschko retired from the sport a few months later.

"AJ might have had a couple of moments against Wladimir Klitschko, but let's be honest, 'Wlad' was no spring chicken and hadn't boxed for 15 months. Wilder is younger, fresher and hungrier. Or at least he keeps telling us that," Froch said.

"Josh always excites but against Wilder it will be way bigger than the rest. That is why I want Wilder to destroy Ortiz. If he does, all of a sudden people won't just be trying to pick which round Josh does it in. Of course, I expect him to win, but it will be a 60-40, maybe even a 50-50 fight."
