Michael Pirotton is ready to shock Johnny Fisher when they fight at London’s Copper Box Arena this Saturday, live on Sky Sports.

The "Romford Bull" is hugely popular, while his Belgian opponent is comparatively unknown. But Pirotton is convinced he can use that element of surprise.

"I'm nobody in boxing," the Belgian told Sky Sports. "Nobody knows about me. That's my only advantage. I know I'm supposed to lose."

Fisher is a strong, come-forward fighter. "He's really aggressive and I can move. It's a classic heavyweight match-up. A bull against a matador. Let's see who wins," Pirotton said.

"The pressure is on his shoulders. He's just the money cow. He didn't grab anything he had. I know whatever happens I've grabbed everything I have."

Pirotton, who's never been dropped or stopped, warned Fisher: "He can't knock me out. I'm able to punch. But I've never been able to punch like I'm really able to punch. And now I feel free to unleash my power."
