Size won't matter - Manny

Manny Pacquiao insists size will NOT matter when he climbs into the ring with Ricky Hatton.

The Pac Man will be by the smaller man when he fights at light-welterweight for the first time, live on Sky Box Office.

Hatton and his trainer, Floyd Mayweather Snr, have both pointed to the size difference - even though Pacquiao destroyed Oscar de la Hoya last time out at welterweight.

The Mancunian is comfortably the best at 140lbs in the world and his only defeat came against Flody Mayweather Jnr at 147lbs.

But Pacquiao, who has already won world titles at five different weights, is confident he can end that impressive record come May 2.

"I feel very comfortable at 147, 145 or 148lbs," he told skysports.com.

"Maybe he is bigger than me but it's not about the size - it's about how you punch and how you win the fight."

"It's a good match for me because our style is similar, we both want action in the ring. Ricky Hatton is also a good fighter, he's strong - but I have trained hard for this fight.

"It depends how hard he trains."

Pacquiao also believes the fight could well be decided by who's left makes it's mark.

As a southpaw his straight left has done serious damage to some of the biggest names in the game, while Hatton's own trademark punch is the hook to the body.

"His left hand, the uppercut and the left hook," Pacquiao explained when asked about Hatton's main threats.

"Of course he believes it's his left hand, but I believe it's mine. Heart decides it. Heart and how we train for the fight."
