PAUL BUTLER has accused big fight rival Zolani Tete of lacking bottle.

The skilful Ellesmere Port boxer challenges for the South African's IBF Super-Flyweight title at Liverpool's Echo Arena on Friday night, sounding the first bell of a big weekend on BoxNation.

If he wins, undefeated Butler will be the first British boxer to drop a weight and win a second world title since Bob Fitzsimmons more than a century ago.

Butler, 26, took the IBF Bantamweight crown from Stuey Hall last summer, but relinquished it when the chance of glory at his natural weight cropped up.

He was left fuming by Tete last year when their contest was delayed because the champion suffered a hand injury.

Butler has also studied Tete's fifth round stoppage defeat in an IBF Flyweight title challenge against Moruti Mthalane in September 2010, where he showed a lack of hunger when the going got tough.

Butler who has won all 17 fights said, "the plan is to jump on him from the bell but not stupidly jump on him.

"It will have to be educated pressure and it's going to be something people haven't seen from me before.

"I  believe I will stop him but if it goes to points then no problem.

"He's bottled it before, I don't like to use that word because you've got to have bottle to get in the ring, but he has done it and if you've got that in you then it will always be there.

"He's going to be a lot tougher than Stuey Hall, who toughed it out a lot, and he's got a much better boxing pedigree."

Incredibly Tete admits he did "quit" against Mthalane, although he has proven himself since as a formidable champion who wins on the road.

His won an IBF eliminator against Juan Carlos Sanchez Jr in Mexico in November 2013 and won the title in Japan last July by outpointing Teiru Kinoshita.

Tete, who celebrates his 27th birthday on Sunday, told BoxNation, "I did quit against Mthalane, but I had no one to train for me and took the fight at four weeks' notice.

"I was saving myself for another day and would never do that again. I have proven myself since.

"If Butler is still around after eight rounds I will give him credit because I am going to knock him out."

Butler fired back at their fiery head-to-head press conference, "he has 16 knockout wins, but that wasn't against the greatest competition."
