Amir Khan believes his domestic rival Kell Brook is bitter over his success.

The two former world champions have been feuding for years, but they will finally settle their differences on February 19 in Manchester, live on Sky Sports Box Office.

Khan explains that their their rivalry first began due his accomplishments.

"What I've done in the sport. The name I've got. You can see how bitter he is. My celebrity status? That comes because of what I've achieved in the sport of boxing. It's not because of other things," Khan said to Sky Sports.

"I have put on great performances, won world titles, made a name for myself in America. It all comes from boxing. How can you hate on that? I have capitalized on what I've done in boxing. He hates that. He can hate me as much as he wants. Once I beat him, he will hate me even more! Now I know that he hates me, it will only make me train harder."

In the opinion of Khan, Sheffield's Brook is not on his level and that will be the key difference on fight night.

He views his own record as being vastly superior when compared to Brook's.

"This is a step down for me. Me going into this fight is going down a couple of levels. There are bigger names, tougher fights. But I had to give this to the British fans. So I've had to step down to give him a beating and show the British public who the best is," Khan said.

Khan has been out of the ring since July of 2019, when he easily stopped Billy Dib. Brook saw action in November of 2020, when he suffered a knockout loss at the hands of WBO welterweight champion Terence Crawford.
