Haye: If I lose to Enzo my career is over.

That's a lot of pressure to put on himself. He could get hit with a lucky punch, sustain a cut etc. He's still young and should be able to bounce back if he were to lose. Perhaps the between the lines version is "If i lose to this guy i'll have to stop believing my own hype and retire".;)

I don't understand why he has all the drama in this or even came out with the comments like that?

2 sell it...
its like the retirement matches in Wrestling lol
