According to his manager, Ignacio Beristain, Juan Manuel Marquez’s much anticipated rematch with Manny Pacquiao may be in jeopardy.

The Marquez camp want a guarantee of $1.5 million, and according to reports have only been offered half that amount for the hotly anticipated rematch.

Beristain hopes to have a deal concluded in the coming weeks, but warns if a deal satisfactory to the Marquez camp cannot be struck then the fight could be cancelled.

Marquez – a noted fitness fanatic – is reportedly now deep into training, reports which are cause for concern for some of those surrounding the Phillipine featherweight.

Reports from the Phillipines have indicated that there is concern about Pacquiao’s dedication to the task, as evidenced by the fact Manny Pacquiao is not due to report to trainer Freddy Roach in the USA until January 8 to begin preparations for the rematch.
