Carl Frampton will have too much for Scott Quigg on February 27, according to the former world champion beaten by both.
Kiko Martinez has two defeats to Frampton on his record, one a ninth-round stoppage and the other a wide points decision when he lost his IBF super-bantamweight title in Belfast 18 months ago.
A shot at Quigg's WBA belt ended more spectacularly as he was knocked out inside two rounds, but that has not stopped the Spaniard backing Shane McGuigan's fighter to leave Manchester with both belts later this month.
"Frampton will win against Quigg,'' Martinez said. "He's the more complete boxer. He is stronger as well."
Martinez has rebuilt his own career since losing to Quigg in July and has a world title fight of his own on February 27 against Leo Santa Cruz, another former champion at 122lbs who now holds the WBA Super world featherweight title.
Unbeaten Santa Cruz will go in as a big favourite, but Martinez is convinced he can pull off an upset before targeting the winner of the huge Sky Sports Box Office fight between Frampton and Quigg.
"Some people don't think I can fight because I lost to those guys [Frampton and Quigg]," he said. "But they are wrong. I am as determined as ever. I'm going to fight a great fight and come out with a victory.
"I would like to stay at this weight because I feel much stronger. But I would definitely love a rematch with Frampton or Quigg."
Carl Frampton vs Scott Quigg, exclusively live on Sky Sports Box Office on February 27, is available to order via Sky remote and online.
