Calling tonight's fight between Anthony Joshua and Wladimir Klitschko is easier said than done.

While many expect Joshua to cruise to victory, it would be impossible to completely rule out the idea of Klitschko inflicting the 27-year-old's first career defeat.

Age and speed is certainly with Joshua, who has demonstrated in each of his 18 KOs just how devastating and powerful he is.

But Klitschko has experience on his side. The Ukrainian knows he can't match Joshua punch for punch and will have to use a methodical approach for the fight.

A number of big names in boxing have given their predictions over the past 24 hours, with Tony Bellew expecting Joshua to record his 19th KO within the first four rounds.

"I'm hoping for a Joshua win," he said. "I think if he goes out there and does what he's been doing to his previous opponents, then he wins inside four rounds."

Carl Froch and Ricky Hatton have similarly predicted the IBF world heavyweight champion will KO Klitschko, albeit at different points in the fight.

FROCH: "If I had to gamble, and I'm not a gambling man, I'd say Joshua knocks him out. This is his acid test. It's a fight he could and should win."

HATTON: "I think it's the right fight at the right time. There are a lot of miles on Klitschko's clock. If Anthony goes in there and gets off to a good start, he could stop him around rounds six, seven or eight."

Amir Khan has now had his say on the fight and while he thinks Joshua will win, he believes it could be decided on points.

Khan, speaking to the Mirror, predicted Joshua to unleash hell on Klitschko but that the 41-year-old will last the whole 12 rounds.

"People say can AJ can take a shot or can he be like Lennox?" the Brit said. "It's his time now and I think he can show that by putting a beating on Klitschko."

In fact, Hughie Fury appears to be the only former/present boxer who thinks Klitschko will win at Wembley Stadium on Saturday night.

When asked for his verdict, Tyson Fury's cousin simply predicted a victory for the underdog.
