World champion Lee Selby is unfazed by Josh Warrington's win over Hisashi Amagasa and remains adamant he is a cut above.
Warrington (23-0-KO4) moved a step closer to challenging IBF world featherweight champion Selby (23-1-KO8) by outpointing Japan's Amagasa 117-111 118-111 120-107 in Leeds on Saturday night.
But Selby told Sky Sports afterwards: "It'd be easy work for me. It was decent to watch but there are levels to this game.
"Before the fight, I said I don't think he's world class and after the fight, I still say he isn't world class.
"He boxed well, trying to get in range and work the body. Amagasa was awkward, tall and rangy. It was a decent fight to watch.
"Warrington was working in this studio for my fight against Fernando Montiel, who's a three-weight world champion and proven at elite level.
"He said that during my Montiel fight, he took three pages of notes about me. I took all I needed to know about him tonight and wrote it on the back of a postage stamp.
"I know he can't punch, has limited boxing ability and if he got in the ring with me, it could end disastrously for him."
In addition to Warrington, Selby has been touted as a potential opponent for fellow world champions Vasyl Lomachenko, Gary Russell Jr and IBF super-bantamweight king Carl Frampton.
