Campbell has urged Joshua to pounce whenever he gets the opportunity in the fight and be sure to throw several combinations in a bid to damage his upcoming adversary. "Tyson is big, and he's long, and he'll make it awkward. I think the only way that I can see Joshua having success is if he gets his feet in distance, and then he's got to throw combinations," the boxing icon revealed to Mirror Fighting.

"He's got to go, he's got to go twice or three times every time he throws. He can't just throw the one shot or the one-two. He's got to go again and again. I think he's got to put it on Tyson if he wants any success. But if he if he leans over his front foot like he did in his last fight, he'll just walk straight on to Tyson's lead hook."

Campbell, like many boxing purists, believes the mammoth dust-up has come rather later than it should have, but will still be glued to the TV on December 11 nonetheless. "I think it's reality. With Tyson and Joshua, I think they're both past the the best, and I think that's reality.

"You've only got to look at the the performances to say that. It's a fight I would have loved to have seen 5-10 years ago, but it's still an interesting fight that's. It's finally happening, brilliant! But I would have loved to have seen this when they was both in the prime."
