**Editor's note: Quillin overweight on the scales, and so no title on the line**
ANDY LEE has revealed that becoming a shock world middleweight champion has sent his confidence soaring.
The Limerick man, 30, saved his career in December when he won the WBO belt in an upset round six stoppage against previously unbeaten Russian Matt Korobov in Las Vegas.
Last June, Lee displayed incredible heart pulling out a stunning right hook to poleaxe John Jackson when he looked on the brink of defeat.
He will need his famous Irish fighting spirit in his first defence against Peter Quillin, fought out in the American's Brooklyn back yard on Saturday night, which is LIVE from 1.30am on BoxNation.
Lee said, "there's been a huge weight lifted off my shoulders since winning the world-title.
"It's what I always wanted to do and I've been touted as a champion for years. If I had never got it I would have been disappointed.
"Now the monkey is off my back and I can just box and show people who I am."
Lee's career now is the polar opposite of a horrendous 2012 when his world caved in.
First he suffered a stoppage defeat in a WBC title fight against Julio Cesar Chavez Jr in June 2012, when he failed to cope with the Mexican's superior strength and lost in seven rounds.
Four months later his mentor and trainer Emanuel Steward, whose house he lived, in passed away.
With his future on the line, he rediscovered his mojo by teaming up with Londoner Adam Booth, who is best known for guiding David Haye to cruiserweight and heavyweight titles.
Lee's only other loss is a stoppage defeat against gatekeeper Brian Vera in 2008, which was avenged in 2011 when Steward was still alive.
Lee added, "we've made unbelievable progress in the last year on my skills and everything has really just clicked for me and my team. Now we're seeing the results in the ring.
"We've made physical and tactical improvements in the gym since the last fight and hopefully they'll show up in the ring on Saturday.
"I think this could be a technical fight or it could be a bit of a fire fight. It's going to be a little of both at times.
"There will be moments where we're looking at each other, figuring each other out, but once we exchange it could be explosive."
Quillin will have plenty of support at the Barclays Center, but Lee believes that his opponent will be the one feeling the heat in his home borough of the Big Apple.
Lee says, "I'm very proud to be an Irishman from Limerick defending his world championship in New York, it doesn't get much better than that.
"Fighting at home like Quillin brings a different kind of pressure to the table. It's the pressure of expectations and people you know coming to the fights.
"I haven't needed to build confidence for this fight. It's not time to think, it's time to do what I've been doing every day in the gym."
Quillin gave up the WBO title when he was ordered to fight Korobov, losing a $1 million payday. It was then that Lee pounced.
Against Jackson, Korobov and, in March 2011 against Craig McEwan, Lee has won after trailing on points.
Quillin says, "I never trailed in a fight and came back to win like Lee.
"I've just won all the time, right out of the gate. Those other guys aren't 'Kid Chocolate', so I think that's why this fight was made."
