Will Hatton be beaten at 140?

I'll admit, I am a Ricky Hatton fan. But even I started to question his ability after the loss to Mayweather and his win against Lazcano, where he struggled to hit top gear and was hit by some heavy shots. albeit winning comfortably in the end. Had all those years of drinking and ballooning up and down in weight had an effect on his performances? He needed a change of trainer to revitalise. I saw Billy Graham as more of a mate instead of a trainer, especially in the last year or so of their partnership. Now Floyd Mayweather Snr seems to have got him focussed more on the basics again. He used his jab better last night, and he didn't rush in like he may have done 6 months ago. Anyway, I'm rambling. My question, can you see Hatton being beaten at 140 pounds? And by who? Personally I think he is quite clearly the best fighter in the world in that division and the only way he'll suffer defeat again is if he moves up to Welterweight. Thoughts?
