“This is my time and no one is taking this title away from me. I am going to beat Martinez on Saturday night at The O2 for everyone at Sky.”
“Saturday night, we put it all on the line, We’re just going to box. You can talk a lot before the bell goes but I’m not the person to do that.
“We’ll see what happens, we have small gloves on, the better man will win. Inside the ring is where the talking is done, where it matters.
“When the pressure is on, the cameras are on, I enjoy it, pressure is good, it creates diamonds.
