Amir Khan is confident he is better than ever ahead of his world title challenge against Ternece Crawford.
Khan takes on the welterweight champion at Madison Square Garden in New York on April 20.
And the Brit believes he can upset the odds and become a two-weight world champion.
"It will be amazing to be the new welterweight world champion and to be a world champion for a third time," he told BT Sport.
"And to be one of the best pound for pound fighters in the world, you can't get better than that. I know I'm within touching distance and I just need to go in there on April 20 and put on a great performance.
Terence Crawford trolls Amir Khan ahead of world title fight
"I feel I'm better now than I've ever been. I'm more experienced and smarter as a fighter, and the speed is still there; people say the speed disappears as you get older but the speed is there.
"I've got stronger as well and I'm more professional; I can't take the shortcuts I took when I was younger."
Crawford has yet to lose as a professional and has won world titles in three weight divisions.
But Khan believes he is being overlooked and that there is little between the two.

He added: "There's a year apart in age so he's not the young spring chicken perople are saying. I feel my speed, movement and IQ... and I do really well against southpaws.
"Whatever he brings, I'll have the answer, whatever he brings to the table we'll be ready for.
"I know I'm fighting someone who is at the same level at me, who is at the world class level."
