Kell Brook may be the number one contender for the IBF welterweight title but it seems he still has his heart set on facing fellow Brit and former world champion Amir Khan.

The Sheffield fighter secured the 29th win of his career when he cruised past Argentinean Hector Saldivia on Saturday night thanks to a third round knockout.

Brook was rarely troubled as he floored his opponent in the first round before a stiff jab and a short left hook in the third sent Saldivia to the canvas once again and referee Howard Foster brought an end to proceedings.

The undefeated welterweight was asked immediately after the bout whether he wanted to face Khan and it was clear from his response that the Bolton boxer is still on his mind.

"Khan is going to get schooled if we meet," said Brook. "That is a silly question. I am going to be on him, relentless and I will take him out."

Brook is now the mandatory challenger for the IBF title which was won on the same night by Devon Alexander who was awarded a unanimous decision to claim the belt from Randall Bailey.

The American became a two-weight champion but it seems that Brook may well attempt to first land a shot at Khan who is next in action against Carlos Molina on December 15.

"In my mind I'm boxing for a world title but don't rule out Khan or [Ricky] Hatton, anything can happen in boxing," Brook told Talksport on Monday morning.

"It will always be unfinished business [if I don't face Khan]. With me and him it's personal and I'm passionate about that fight. I'm passionate about knocking Amir Khan out.

"We were on Ringside the other night and there is something about him which really gets to me. People having been talking about me and him for years and I just want to retire him.

"He's distasteful with some of the things he says. I just want to take him out. I think it's going to be a blockbuster for the fans. He only fights in America but I'd love to fight in a big stadium over here. If we can make that happen I'm sure I can take him out."

Khan has stated that he is only interested in fighting for world titles and it may be easier for Brook to land the fight if he has a title at welterweight.

Another name being mentioned as a possible opponent for both Brook and Khan is the returning Ricky Hatton. The former two-weight world champion could soon have the chance to land another title belt after Paulie Malignaggi said he was prepared to face the Brit.

"It would be an honour to fight Ricky again," the New Yorker said after holding on to his WBA welterweight title with a hard fought points decision over Pablo Ceasr Cano.

Hatton defeated Malignaggi back in 2008 with an 11th round stoppage and is returning to action for the first time in more than three years when he faces Vyacheslac Senchenko in November.
