“He’s beatable,” said Butcher, who lost to still-undefeated Kevin Satchell for the British belt at flyweight in 2013. “He stepped up to world class and got well beat. He went from fighting Luke Wilton in a British title eliminator to fighting for the world title. I think that he knows he doesn’t belong at that level and he’s got a lot to prove, but so have I.
“Fair play to him for taking the chance but other than that fight he’s not boxed anyone and this is an even fight and one that I can win comfortably – I’m very confident.”
“Charlie is a Matchroom guy so they’re putting him in there expecting him to be the massive favorite. I want to go out there and shock them and show Matchroom that they picked the wrong man.
“These are the fights I want to be in and for everyone saying he is the favorite I think it’s a great 50/50 fight.
“We used to kick about together, we sparred a lot, spent a lot of time together and even roomed together. I know him well and there’s no animosity, its business. We’re in the same weight division and we want the same thing, so the fight was inevitable.
“I’ve got a lot of respect for him and as a fighter, but I’m looking forward to winning the British title. He’s a tough lad and can really box, but I’ve got the will to win in there and I think that will be the difference.
“I know what to expect from him and what his strengths and weaknesses are. Things have changed for both of us since the days we sparred.”
Butcher’s clash with Edwards is part of a huge night of action in Glasgow led by the 140-pound IBF/WBO unification battle between Ricky Burns and Julius Indongo.
