Since when is Hatton retiring? He's got a fight with powderpuff next followed by possible fights with Pac and the like.
I don't really see the comparison at all to be honest.
Hatton just fought in front of 55,000 adoring fans. Naz, over a year after the Barrera loss, chose Manuel Calvo as a comeback and looked so piss poor, and so clearly out of love with boxing, that he was booed out of the ring, never to be seen again.
Apart from being Brits that have/had great careers.. i don't see it.
