Macau, China - Rumors are circulating that Saturday's HBO Pay-Per-View could set the stage for a 2015 showdown between Top Rank fighters Manny Pacquiao and Jessie Vargas.

Pacquiao headlines the card, when he defends his WBO welterweight title against undefeated Chris Algieri, who is also the WBO champion at 140-pounds.

Pacquiao-Algieri takes place at a catch-weight of 144-pounds, which is viewed as the first step to the Filipino star dropping down to junior welterweight.

On the undercard, Vargas (25-0, 9KOs) will defend his WBA 'regular' junior welterweight title against former 135-pound champion Antonio DeMarco (31-3-1, 23KOs).

Freddie Roach, who trains both Pacquiao and DeMarco, has no idea why people are talking about a potential Pacquiao-Vargas fight in 2015 - because he is confident that DeMarco will dominate and knock Vargas out.

"Jessie Vargas is going to get knocked out on Saturday night, so we don't have to worry about that. DeMarco is going to kick his ass," Roach stated.
