Of course Haye is obsessive about fighting Vitali, he doesn't want to go out leaving his reputation stained as it is.
But he might be too late, Vitali might not want to give him the shot anymore, and even Haye acknowledges this fact (even if it annoys him immensely).
Haye had too much bravado and arrogance towards the champs, and it comes back to bite him eventually. Time might have caught up with this arrogant hype job. Too bad, for boxing too.
