Juan Manuel Marquez would be interested in a fight against Kell Brook, according to his agent Ignacio Beristain.
Brook is the heavy favourite to defend his IBF welterweight title against Jo Jo Dan tomorrow night, which will be his first fight since he won the title six months ago.
Marquez, 41, is currently struggling with a knee injury, but Beristain thinks that he would be interested in a fight with the winner should he opt against retirement.
He told Behind the Gloves: "Definitely that's an interesting fight, but that's something that the promoters have to talk about. Fighting the winner makes it interesting. But here in the States, going to the UK - impossible."
Marquez has previously beaten Manny Pacquiao.
