Amir Khan will have the odds stacked against him when he gets in the ring with Crawford; the American is not only undefeated professionally, but he is widely regarded as one of the best boxers in the world.

Ahead of tonight’s tussle, Khan has insisted his “skill” and “IQ” will help him overcome the American WBO welterweight champion.

He said: “For me to win this fight I have to be on my A-game and make no mistakes.

“I’m not going to go in there thinking I’m the bigger fighter, my skills will win me this fight, not my size or my power. My IQ will win this one.”

He also told BT Sport: “I’m a fully-fledged welterweight who hits hard. I’m an unbeaten welterweight fighter and it’s the weight I feel comfortable at and that I feel strong at.

“I’ve got the perfect size whereas the other weights might have been too much for me, like when I fought Canelo Alvarez.”

Crawford has praised Khan for his undefeated record in the welterweight division and has stated facing him is going to be “tough”.

He stated: “This is a big fight. Amir Khan never lost in the welterweight division. He knows what he is doing in the ring.

“He boxes really good. He is really crafty. He is a veteran. His is going to be a tough fight.

“I go into the fight looking to get the win. If the knockout comes it comes but that’s not what I am focusing on or looking at.

“It is boxing so anything can happen. We prepare to go 12 hard rounds and that’s the way we are going to take it.”
