British rivals Amir Khan and Kell Brook are finally going to settle their differences on Saturday, at the Manchester Arena.

The two boxers have been trading verbal shots for years, with a finalized deal never in sight - until now.

The loser will be on the brink of retirement.

Khan has been out of the ring since July of 2019, when he easily stopped an overmatch Billy Dib.

Brook saw action in the fall of 2020, when he suffered a four round stoppage loss at the hands of WBO welterweight champion Terence Crawford, who helped Khan prepare for Saturday's fight.

Although the two British boxers are around the same age - Khan believes Brook is way past his best.

"It’s a business, it is what it is,” said Khan. “Why not? He’s still Kell Brook, he still talks the same, he still feels the same way about fighting me and he still feels that he can beat me. I just don’t think he has it in him. He’s not the same Kell Brook he was before. A couple years ago, he would’ve given me a harder fight for sure.

"But now, he doesn’t have a chance. It’s probably better fighting him now because he’s already half-broken. Beating a Kell Brook now or beating him five years ago, I don’t think it makes a difference.

"When people read on my resume that I fought Kell Brook, they aren’t going to look what year that was so I don’t think that matters now. Kell has no chance of winning this fight. I’m going to destroy him, and it’s going to be a masterclass. The way I destroy him, he’ll need to retire after that, this will be his last fight."
