Freddie Roach isn't a stranger to the sport of boxing. The 59-year-old Hall-of-Famer knows when someone is afraid to fight, and he knows that Manny Pacquiao's recent match spooked Floyd Mayweather Jr.

According to the American trainer, Pacquiao's recent performance against former unbeaten fighter, Keith Thurman, had alarmed Floyd. He said that he thinks that "Manny scared him a little with that performance."

He also observed that the undisputed welterweight champ left the arena before the decision was announced. Mayweather Jr. didn't stay at the fight like "he usually does," quipped the legendary trainer.

"Money" was ringside when Manny Pacquiao exchanged blows with the former super welterweight champ. After the end of the rounds, Jr. left the arena with his posse, going before the official announcement was cast by Jimmy Lennon Jr.

In 2015, Floyd Mayweather Jr. bested the Filipino icon in a unanimous decision win. After the match, Pacquiao revealed that he was fighting with an injured shoulder, something that has irked the American boxer since.

After their fight, the unbeaten American boxer went to retire, while Manny pushed on to win 5-out-of-6 bouts. His only loss came from a controversial decision against Jeff Horn at Suncorp Stadium in Brisbane, Australia.

Outside of boxing, Mayweather recently fought Japanese kickboxer Tenshin Nasukawa Rizin in a 2018 year-end match at the Saitama Super Arena in Japan. He also fought against former UFC champion Connor McGregor in 2017, resulting in 10-round KO win against the rambunctious Irishman.

Recently, the two future Hall-Of-Famers were embroiled in an online war of words, as Floyd accused Manny of riding in his popularity. Jr. said that the fighting senator's entire career had been associated with his "name."

The new "super" welterweight champion replied by saying that Floyd came to his "fight and used his name in a post." The 8 division champ ended his statement by saying, "if you want to be relevant again #MayPac2."

After his impressive performance against a former undefeated champion, there have been talks of a possible rematch between the two polarizing boxers. However, Mayweather has continued to maintain that he's not interested in another fight against Pacquiao.

For his part, Manny has said that he isn't planning to fight until 2020. His possible opponents might be the winner of the Errol Spence versus Shawn Porter match on September. His camp has also bared that they are interested in fighting Mikey Garcia in the future.
