Tyson Fury has vowed to be more aggressive than he's ever been when he fights Dillian Whyte next month.

Fury will put his WBC belt on the line in all-British heavyweight bout at Wembley Stadium on April 23.

The unbeaten 33-year-old has claimed the fight in London will "100 per cent" be the last of his brilliant career.

If that is the case, Fury says he will sign off in style at the expense of Whyte.

"I'm going to try and come in the heaviest I've ever been," Fury told Sky Sports News. "Biggest fight - so I'm going to be the heaviest, strongest, fittest, more aggressive than I've ever been.

"I'm looking for the knockout. No secret, there's no point in me lying about gameplans. What I'm going to do, is I'm going to come straight to the centre of the ring, back him up and land big heavy punches on him until he's knocked out."

Fury does not expect the fight to go the distance.

"I think someone's getting knocked out," Fury said. "Whether it's going to be me on the front foot or him on the back foot, someone's getting chinned.

"Every heavyweight poses a threat because they're all big men, they can all knock another man out.

"It's something that I'm looking forward to, the challenge, if he can knock me out, good luck to him. If not, onto the next one."
