WBC featherweight champion Gary Russell Jr. is not convinced that Josh Warrington, the IBF champion, would face him in a unification clash.

Russell is back on Saturday night, when he defends his world titles against former champion Kiko Martinez at the Barclays Center in Brooklyn, New York.

Warrington (28-0, 6 KOs) has a mandatory defense coming up on June 15th, when he collides with undefeated challenger Kid Galahad.

Russell (29-1, 17 KO) only has one loss on his record, which came by decision at the hands of Vasiliy Lomachenko.

"Would Josh Warrington be willing to put his title on the line against me in a unification bout? I take my hat off to him, he's a tremendous come-forward pressure fighter but he lacks punching ability, that's very dangerous against Gary Russell Jr. I have hand speed but I also can punch, I have many more knockouts than Warrington, the hand speed is blazing fast and blurry, the shots that hurt are the ones you can't see," Russell said to Sky Sports.

Martinez, a huge underdog coming in, believes that he's capable of hurting Russell when they exchange.

Russell has other ideas, stating that Martinez's abilities will not be enough to come away with the win.

"I'll do what I'm accustomed to doing and that's being the best Gary Russell Jr there is," Russell told Sky Sports. "He [Martinez] is aware that he is competing against one of the best in the world. If you Google the fastest hands in boxing, my name will pop up.

"Our styles will blend perfectly because I'm never in unfamiliar territory, I've been competing against every style possible, being an elite athlete and I'm now becoming an elite world champion. He [Martinez] is slow on his feet but is strong with a good punch, he will bring his physical best and will be on his A game but that won't be enough."
