I hate to say it but Hatton is finished, deep down he knows it too but until he figures out what to do with himself beyond boxing a comeback will always be on the cards.
Unfortunately it's very possible that this fight might happen due to economics. Mayweather has always said that he regretted not fighting over here (The UK) and a re-match would sell out Wembley Stadium with 100,000 people not to mention the PPV. It would make both of them and all the hangers-on a colossal amount of money, much more than a Mayweather v Pacquaio fight. I really hope Hatton doesn't take it though as he'll be embarrassed, besides he looked in awful shape the other week on Soccer am.
