Dillian Whyte says he is “well up” for a fight against Johnny Fisher and has vowed to stop ‘The Romford Bull’ inside four rounds.

The Brixton heavyweight was watching from ringside as Fisher battled to a majority-decision victory over Michael Pirotton at The Copper Box on Saturday night.

Whyte is ready to return following his loss to Moses Itauma last August and has welcomed a verbal challenge from Fisher.

“Johnny Fisher has been calling me out for a while. He wants to fight me. I’m well up for that fight,” Whyte told Sky Sports.

“I knock Johnny Fisher out. It’s heavyweight boxing, anything can happen. I could get caught high on the head like I did last time out, but I’ll knock Johnny Fisher out.

“I’ll be surprised if it goes past three or four rounds. I’m an ageing dog but I still have all of my teeth.”

Whyte, who holds wins over the likes of Joseph Parker and Alexander Povetkin, insists he would relish an explosive showdown with Fisher, who has 12 knockouts in his 15 victories.

“He’s a bit erratic and he’s open in lots of areas but he’s dangerous,” said Whyte. “He’s swinging big punches, a big man, and he hits hard so yeah, I think it would be an exciting fight while it lasts.”

Asked about Fisher’s biggest threat, Whyte added: “Big overhand rights really. That’s it really, but I’ve fought the best of my generation. The reason this fight attracts me is because it’s dangerous. My last fight lasted a round so people could be thinking I’m washed up and finished now so let them run with that.

“I don’t mind being a stepping stone because you need a stepping stone to step somewhere else. Let’s go. They want to fight me. I was at home relaxing, they offered me out, so let’s get it on.”

Nelson warns Fisher about Whyte threat

Sky Sports expert Johnny Nelson has warned that Whyte could be ‘too much’ for Fisher.

“No he can’t [keep having fights like that],” Nelson told Sky Sports.

“I spoke to Dillian Whyte, who is kind of looking at being a potential opponent for Johnny Fisher.

“I think Dillian knows too much for him, regardless of what stage of his career he’s at.

“They need to think smartly, matchmaking him, if they want to get him to a British title attempt.

“I wouldn’t put him in with Dillian Whyte, because Dillian knows too much.

“He’s strong, he’s rugged and he’s experienced.”
