In a recent interview, Amir Khan called for a long awaited showdown with his career rival, Kell Brook.

The two former champions have been discussing the possibility of a fight for several years, but nothing ever came together.

Brook was in the ring back in November at the MGM Grand's Conference Center in Las Vegas, and got knocked out in four rounds by WBO welterweight champion Terence Crawford.

Khan has been out of the ring since the summer of 2019, when he knocked out late replacement Billy Dib.

Brook is not fully convinced Khan is serious about the fight - but he's ready to jump on board if the challenge is legitimate

"I don’t know if it’s a publicity stunt of if he does actually want it. It sounds like he does and that’s music to my ears. It’s a fight that everyone’s wanted for a long time, so if it does happen, happy days. I think it’s clear that I want the fight," Brook said to Talk Sport's White and Jordan show.

"It just caps the career I’ve had, to be in a fight such as that – the highlight of the career. I believe they [the fans] still want it. If we can get it across the line and it can happen, I think it’ll definitely catch fire again once we start promoting the fight. And what a fight it’ll be.

"There’s only one winner and that’s me. I’m confident I’d knock him out, definitely yeah. It’s always been me and, as soon as he’s signed that contract, he’ll know pretty quick as well. I’ll be taking that win. I’m just confident in that fight, I’ve seen his fights and I just believe that it’s a great fight us meshing together. I just believe that I’ve got the shot and I’ll find a way to catch his chin and end the night. I’m confident I’d knock him out, definitely yeah.”
