Reigning WBO middleweight titleholder Andy Lee has a big fight ahead of him on Saturday, as the Irishman heads to Manchester for a clash with England's Billy Joe Saunders, an undefeated contender who, like many are, is probably a better pure boxer than Lee.

But Lee (34-2-1, 24 KO), while confident that his power will carry him through, doesn't feel he'll need to rely on that power alone against Saunders (22-0, 12 KO).

"I have a punch that can end a fight, lights out, in any given second," Lee said. "I won't rely on the punch. I will look to dominate from the start with educated pressure. I'm feeling very dangerous at the moment."

Saunders, 26, had to survive last year to beat Chris Eubank Jr, and since then has fought just one time, a stay-busy bout in July against a club fighter with a sub-.500 record. Lee, 31, sees Saunders as protected.

"Saunders' unbeaten record is a disadvantage. He's always been in fights he's expected to win and has been well managed by (Frank) Warren," Lee said, adding that Saunders doesn't have the necessary tools to beat him.

"I've never lost a fight on points and I never will on points. If I'm down on the cards I will go out swinging in the last round. ... At the end the day it's about how good you are and he's not good enough to beat me."
