Promoter Eddie Hearn believes Carl Frampton's world title credentials will come into stark focus at the Odyssey Arena tonight.
While Hearn is confident that Frampton can pass his hardest test so far when challenging European super-bantamweight champion Kiko Martinez before an expectant crowd, the Matchroom boxing boss nevertheless says the Belfast man will be entering new territory in the ring.
"When you get to this stage everything that we have been building is on the line, we've gone from 5,000 to 7,000 fans, maybe even more depending on the walk-up, to derail that now would be awful and it could happen because this is the kind of fight this is," said Hearn.
"But these are the fights that the broadcaster wants, the fans want and at the end of the day if you can't beat Kiko Martinez you can't win world titles in my opinion and unfortunately for Carl he's facing Kiko Martinez at a time when he is in the best physical condition that he has ever been in.
"People can say Rendall Munroe beat Kiko but he was only 21 then and Munroe was at his peak and went on to fight for a world title.
"We're going to find out a lot about Carl.
"We're going to find out if he's got a chin, you're going to find out how hard he punches, how tough he is, how strong he is... how skilful he is and I can't wait for it.
"A win and Carl goes to the next level which will be a final eliminator for a shot at the World title or a straight world title fight.
"This where we are at and it's exciting... the way the public has responded has been fantastic.
"I think we have put together a great main event and a great undercard with Martin Lindsay fighting Lee Selby which is a fight which could top a bill on its own."
