The attraction isnt difficult to see. They both make a decent wedge and they both move on with their 'proper' career when the dust has settled win lose or draw.

Say what you like about Haye, he could flog ice to an Eskimo and they'd thank him for it. He makes money, Bellew makes money and so does Eddie. Bellew by comparison couldnt flog a raft to a drowning man, he needs Haye to make the serious bunce.

Haye twats him, Haye goes back to negotiating his way along the path of least resistance with a World Heavyweight title at the end of it. Bellew goes back to defending his cruiser title for a few quid a time before eventually cashing it in.

Should the unthinkable happen and Bellew win, the exact same thing will still happen because Bellew isnt a star and never will be, Haye is and will still have fighters falling over themselves to get in the ring with him.

Temporary embarrasement is all that faces the loser, theres no terminal threat to their career.
