Carl Frampton has started the war of words with IBF featherweight champion Josh Warrington and insists they aren’t on the same level.

The Northern Irishman claimed an emotional victory over Australia’s Luke Jackson at Windsor Park in Belfast last month and he now has his sights set on a world title.

Frampton has been keen to work his way back to world title level after losing his WBA strap to Leo Santa Cruz in January 2017.

He looks likely to get that chance later this year against IBF belt holder Warrington after the pair clashed in the ring following Frampton’s stoppage of Jackson.

Promoter Frank Warren confirmed the pair are working on a date and venue for a mouth-watering all-British affair. And Frampton has already fired shots at the Yorkshireman after claiming he isn’t even close to his level.

Frampton said: “It has to be realised that Warrington’s best win has been against a weight-drained (Lee) Selby who has left featherweight and gone to lightweight for his return which tells you a lot.

“Warrington still couldn’t get rid of him and I would also look back to the trouble he had with Kiko Martinez who was done.

“I would say that some people see it as a more difficult fight than maybe they first thought a year ago — including myself, mainly because of the fact he has beaten Selby so I will have to be physically and mentally at the top of my game.

“It would be a huge moment for me to become world champion again having been written off by so many people after the loss to Leo Santa Cruz and everything else I’ve been through over the past couple of years.”
