Here is what the fighters had to say Thursday:
 
ERISLANDY LARA
 
"I plan on going in there and getting into my zone and making the adjustments that will allow me to be victorious.
 
"One difference between this fight and our last fight is that I'm coming into this fight 100 percent healthy. I'm not making any excuses but I had a fractured knuckle going into our first fight. I still felt I was winning the fight. This time I'm not going to leave any doubt about who is the best.
 
"I have no pressure on me. I feel calm. Part of that comes with experience but I also know that I'm going to go in there and execute my game plan like I always do.
 
"I'm always stuck in controversial fights because of my fighting style.
 
"I'm excited to be sharing the stage with the Charlo brothers. We have trained together, so being part of this with them is great.
 
"Vanes's a lot more passive than he was for the first fight. He was telling me I better be ready.
 
"I'm going to do what I have to do. Put my game plan together, put my punches together, I'm going to do everything that I have to do to be victorious on Saturday night.
 
On how he's improved from the first fight...
"The fundamentals are always there. Every fighter gets better with every fight. You get a little bit more experience and that's the difference."

VANES MARTIROSYAN
 
"I've had a tremendous camp. I have a great team. I've had incredible sparring partners and I can't wait for the real thing on Saturday.
 
"I'm in the best shape of my life and I've never been so ready. I don't have to tell you what I'm going to do up here, because you're going to see it on Saturday night. Actions speak louder than words. This is going to be the best Vanes you'll ever see.
 
"This time around I am definitely going to be more aggressive. I cannot wait for Saturday.
 
"There is a different feeling for me in this fight than ever before. It's for a world title, this is as big as it gets.
 
"It is the 'Dream' versus the 'Nightmare,' and you'll definitely see the 'Nightmare' on Saturday night.
 
On what he saw in Lara's eyes when they faced off...
"A fighter looking at another fighter. I see hunger in both eyes.
 
"A lot of the first fight, I was kind of inexperienced but we've matured a lot throughout the years. Four years into this game, a lot of experience, a lot of knowledge in the game so there's a lot I learned from the first fight.
