Terence Crawford has warned Amir Khan he will be facing the best fighter on the planet when they clash at Madison Square Garden on Saturday.

Three-weight world champ Crawford is ranked No 2 in the pound-for-pound rankings behind Ukrainian superstar Vasyl Lomachenko, who destroyed Anthony Crolla.

The unbeaten American claims he should be recognised as No 1 because he has every attribute needed for greatness.

“I feel I’m No 1 pound for pound,” said the confident WBO welterweight king.

“I can box at range or I can fight up close, whatever’s needed. I can box on the back foot or front foot and I have good sideways movement.

Terence Crawford rates himself as No.1

“I’m a southpaw, who is just as comfortable when switching to orthodox

“I have speed as well as punching power. I’m good defensively. I’m an intelligent fighter, who adapts to any opponent. I’m the best boxer in the world, hands down.”

Khan has likened Crawford to his trainer Virgil Hunter’s greatest charge, Andre Ward, but he shied away from this comparison.

Crawford says he is his own fighter and is focused on beating Khan, who is a huge underdog, to take his perfect record to 35-0.

“Everybody is their own person and everybody has their own purpose, drive, mental ability in the sport of boxing,” he said.

“Focus is one of my strong points because that’s what a put a lot of effort in to, focusing on what I need to do.”

Crawford, 31, has reeled off 11 successive world title wins since his first triumph in March 2014 when he came over to Glasgow to claim Ricky Burns’ WBO lightweight crown.

Crawford was relatively unheralded then and says that points win over Burns was the launchpad for his career.

“That was a big moment for me in my life, capturing my first world title,” he said. “It was a long road for me.

“I remember going over there, but everyone was cool. As I walked out, everyone was booing me, but I didn’t let that bother me. I had a game plan, I stayed strong and got the win.”
