If the fight is real, Hatton should be too big, too strong, and too powerfull for Pacquiao. Hatton is a pitbull who tears off after his opponents and gives them no room to escape or fight back. Hatton has only lost to a defensive counter-puncher (Mayweather Jr.) and Pacquiao has lost 3 times and drawn twice. Pacquiao is no defensive fighter -he is an attack fighter with some defensive skills. Pacquiao has frequently enjoyed the size or power advantage over his opponents with the exception of De La Hoya who did not fight at all but rather covered up and let the little Philipino pepper-spray him for 8 rounds. Yes, Pacquiao did bruise De La Hoya's face after tapping away at him freely, but, when you think of it, a woman can also bruise a man's face if she is let to freely punch away without any return.
So I see Hatton closing the gap on his Philipino opponent and really giving him a battering he will not be able to stop and never will forget. Hatton has mostly had to fight bigger men during his career and this time it should be easier for him to get at the man in front of him without having to deal with the big reach disadvantage. By the 9th or 10th round Pacauiao should be beat and done.
Look, Pacquiao seems to be a decent enough, modest and respectfull man. In most fights I would cheer for him. But he is not white, and this time he's fighting one of my own and I shall not betray my own and shall be hoping for a clear victory for Hatton.
