Nowhere near as well in the UK as Mayweather seems to think. He's always wanted to fight a British fighter again following Hatton earning more than him after Floyd foolishly allowed The Hitman to get 100% of the PPV revenue from Sky Box Office. Khan won't do anywhere near as well as Hatton-Mayweather did on PPV for a few reasons: 1. Khan is known more in this country for his failures than his success. People won't have any faith in him to win. 2. People don't like Khan in this country so won't even want him to win. 3. People in this country find Mayweather's act lame and won't want him to win either- hence nobody will care. So it's unlikely people will pay money to stop up until 5 am watching Khan.
I think people would be surprised how well Khan Mayweather would sell in the UK UK is one of the biggest boxing markets in the world...Mayweather alone would sell big here...especially as his last fight. Khan Mayweather + a few other popular fighters from the US to fight as the co-feature would sell out Wembley easy.
Yeah this fight in the US is not that huge But in the UK it would be pretty damn big I think I wonder if Mayweather would be willing to go to the UK though
