Former world title challenger Michael Jennings wants a second crack at the WBO title - against Kell Brook.

Jennings lost on cuts to Brook in September in the fifth round in Birmingham.

But he believes he could have beaten the young tyro.

And now he is lining up a second shot at the Sheffield star should he win a world title early next year.

Promoter Frank Warren suggested that a rematch between the two could be a goer for 2011, and Jennings is keen to hold him at his word.

"The Brook fight was a massive disappointment," said Jennings.

"Everyone knows that I am a slow starter, and I wasn't at my best in the opening rounds.

"I thought I was just coming into it when I got the cut. It was a bad one and the fight couldn't carry on, but to say I've got unfinished business with Kell is an understatement.

"I want a rematch and I'll be asking Frank Warren if that can happen next year.

"What a fight it would be if Kell did win a world title.

"I may be in my 30s, but I've not had many hard fights, and I'm far from finished yet.
