James DeGale says he is ready to prove the doubters wrong after landing in Boston for Saturday's world title fight against Andre Dirrell.
DeGale has been happy with his Florida training camp but stressed he still had a little work to do to reach peak condition for the vacant super-middleweight IBF title showdown.
He is hoping to become the first British boxer to win an Olympic gold medal and a professional world title and, ahead of the Aggonis Arena date, the Londoner told Sky Sports News HQ: "The whole experience of Miami was fantastic.
"As I said before it breaks things up, it's nice just to get away. When you get away from home you know it's serious.
"It's been nice to get away, but now is the proper countdown. I'm in Boston, it's fight week and it's all go. It's all becoming very, very real.
"I'm pretty busy all week now and fight night's Saturday. I'll be busy, my weight's fine, 4lb over. I'm just raring to go. I'm ready. I'm looking forward to it, I'm focused, my mind's on it.
"I've trained too hard, I've come so far, it's my time to prove all the doubters and haters wrong."
Watch DeGale v Dirrell live on Sky Sports 1, from 8.00pm, this Saturday.
