Amir Khan is confident he will take a "last chance" to revive his career against Carlos Molina this weekend.
The deposed light-welterweight champion goes into the Los Angeles contest on the back of successive defeats which led to a split with trainer Freddie Roach.
And Khan reckons his new partnership with Virgil Hunter has left him in better shape than at any stage of his career ahead of the Sky Live fight.
Speaking to Sky Sports at his training camp, the 26-year-old said: "My opponent's going to come in very confident - I'm coming in off a defeat and he's coming off a win. I'm sure he's going to be up for this fight and he thinks 'Amir Khan's at a low and I'm going to catch him at the right time'.
"But that's not going to happen. I'm at the best time I can ever be. I'm ready for this fight and I'm hungry to get the win. I know now I can make no more mistakes. This is the last chance and I have to put everything together.
"It seems like the jigsaw's complete. I've got a great trainer with me, I'm in a great training camp, I'm nice and calm, I've got a great family behind me and I just can't wait to get in there and get back on that winning streak."
Hunter, meanwhile, believes he can guide Khan back to the top of the light-welterweight division.
He said: "Why not set the bar high? That's what we're together for. The goal is to reclaim 140, to rule it until he grows into a welterweight and take that division over also. That's the goal - nothing below that."
