Amir Khan does not see any way that Kell Brook will be able to topple him in the ring.
The two former world champions will collide in an all-British grudge match at AO Arena in Manchester on February 19, live on Sky Sports Box Office and ESPN+.
The two fighters have been feuding for several years, with many observers believing that a fight between them would never come off.
According to Khan, his Sheffield rival has always been jealous of his success.
"I think Kell Brook is very bitter and this is a good time for me to put the issue straight between us because he has always thought he is the better fighter than me," Khan told Sky Sports News.
"He's always said he should have had the recognition that I had and believes that should have been him. But at the end of the day, my skills made me the name I am today. I'm just a hard worker and beating the big names around the world, coming to America and winning world titles is what got me here and I really never got it easy. Whereas Kell, I think he is bitter and I see a bit of jealousy in him."
Khan believes Brook has lost his ability to take a punch.
In his last fight, in the fall of 2020, Brook was stopped in four rounds by WBO welterweight champion Terence Crawford.
Khan predicts a very dramatic victory, with Brook being brutally knocked out inside the distance.
"I don't think Kell has a chin or can take a good shot. I think his punch resistance is gone, literally gone, and I honestly believe that he is doing this fight just for that payday," Khan said.
"I'm doing this for the public, because it's what they want. If I don't take this fight, people will always say to me 'but you didn't fight Kell'. He says he's going to beat me and do this and that, I hope he tries to. But I just don't see him doing anything. Kell's has no chance of winning this fight, I can honestly say that to you. Come February 19, I'm going to destroy him and it's going to be a masterclass. The way I destroy him, I think he'll need to retire after that. This will be his fight."
