Hall of Fame trainer Freddie Roach held nothing back when reacting to some recent comments from fellow coach Robert Garcia.

This coming Saturday night at Barclays Center in Brooklyn, Roach's fighter Ruslan Provodnikov will defend his WBO junior welterweight championship against undefeated challenger Chris Algieri.

In several interviews, Garcia gave Algieri a good shot of unseating the heavily favored champion from Siberia. In the past, Algieri spent some time in Garcia's gym located in Oxnard, California.

Over the last few years there has certainly been some bad blood between the two trainers.

The tension first began in 2010, when Garcia trained Antonio Margarito faced Roach's superstar pupil Manny Pacquiao. In the pre-fight hype to that bout, there was an incident where a video surfaced with Margarito, Brandon Rios and Garcia making fun of Roach's physical condition due to Parkinson's Disease. Garcia, and his two fighters, publicly apologized afterwards.

The bad blood restarted last November in Macau, when Rios challenged Pacquiao. There were plenty of pre-fight taunts between the camps, especially with Pacquiao's longtime conditioning coach, Alex Ariza, joining the ranks of Garcia's gym and working the corner of Rios. Garcia and Roach verbally clashed at a gym in Macau, and the confrontation exploded when Ariza kicked an incoming Roach.

Then there was an interview back in February, where Garcia questioned Roach's '2013 Trainer of The Year' award .

It certainly was no surprise that Roach took offense to Garcia's recent analysis that Algieri could pull off a big upset on Saturday.

"If any of his guys want it after this - they can line up too. What the f*** does he know about boxing? Who is he.....drunk," Roach told BoxingScene.com in a video interview posted earlier today.

"[Marcos] Maidana gave Mayweather a fight for four rounds and then Mayweather took over. Then his other boy was a punching bag for my guy, Manny Pacquiao. I'm not impressed by either one. We'll fight either one of them if they want to fight us in the next fight."
