At the post-fight press conference to the Manny Pacquiao-Marco Antonio Barrera rematch at the Mandalay Bay in Las Vegas, WBO super feathweight champion Joan Guzman (27-0, 17KOs) was in attendance and issued a challenge to Pacquiao.

"When are you going to fight me," Guzman kept shouting at Pacquiao.

Guzman told reporters that will he take on all-comers and made it clear that he feels Pacquiao is avoiding a fight with him. 

In order to put himself in line for a Pacquiao fight, Guzman must first get past the always dangerous Humberto Soto on November 17. The fight will be featured as the main event of an HBO televised card from the Borgata in Atlantic City. Should he get past Soto, Guzman may very well get his wish by fighting Pacquiao - if Juan Manuel Marquez doesn't seal the deal first.
