Legendary trainer Freddie Roach believes victory for his man Viktor Postol in 23 July’s big unification fight with Terence Crawford will earn him superstardom.

“A win for Viktor will mean that the U.S. and the world has a new star in boxing. A star as bright as boxing has ever seen."

Roach, like Postol, has played down his underdog tag ahead of fight night: "I do not feel that Viktor is an underdog going into this fight. Why should I? In his two toughest tests - Lucas Matthysse and Selcuk Aydin - he didn't just knock them out, he took their will to fight away.”

The Ukrainian Postol has looked solid since switching to Roach’s Wild Card gym and is undoubtedly one tough fighter.

“He broke them down brick by brick. His experience against blue chip opposition has been great preparation for his fight with Terence Crawford.”

Roach is a fan of Crawford but believes his man’s calibre of opponent will stand him in a better position come fight night.

“Don't get me wrong. I have a lot of respect for Crawford. He has a lot of talent. But I think this is going to come down to resumes and I think Postol has fought tougher and better opponents than Crawford.”

In his rise to World Champion, Postol spent valuable time to help prepare gym mate Manny Pacquiao for his fight with Chris Algieri.

“Postol even spent an entire training camp with Manny Pacquiao in 2014 when Manny was preparing for Chris Algieri. Viktor more than held his own against Manny.”

The hall of famer finished: “Crawford is going to find out that defending a title against Hank Lundy and Dierry Jean is a lot different than fighting a fellow undefeated world champion like Viktor Postol!”
