Viktor Postol has continued the war of words with Terence Crawford ahead of their July 23 unification bout.

“The fight I had with Matthysse was a great experience for me. He’s a higher level fighter than Crawford. It’ll help me in this fight and for the future,” explained the unbeaten Ukrainian.

Postol, who holds the WBC version of the Super-Lightweight World Title and Crawford, the WBO Title holder, lock horns in a mouth-watering unification bout live on the Channel of Champions at the MGM Grand in Las Vegas.

‘The Iceman’ believes the switch hitting star has yet to be tested at the elite level: “It’s hard to say if Crawford has fought anyone like Matthysse, maybe Gamboa.”

Trainer Freddie Roach has called this a 50/50 fight and Postol, who was speaking with FightHub, acknowledged it’s a tough task at hand to determine who is number one at 140 lbs.
