Legendary promoter Frank Warren has compared Liam Smith to fellow Brits Joe Calzaghe and Ricky Hatton before the Liverpudlian travels to Dallas, Texas to defend his WBO World Title against Canelo Alvarez.

Unbeaten Smith will be in the lions' den on September 17th when he heads Stateside on Mexican Independence Day to face the fearsome Canelo, 26.

"I know that Liam can fight. I think he’s one of the best young fighters to come out of Liverpool. He’s done everything that’s been asked of him.

"I can think of a few fighters who have been underdogs, like Joe Calzaghe when he fought Jeff Lacy and Bernard Hopkins. Or Ricky Hatton and Kostya Tszyu – no one gave Ricky Hatton a chance," said Warren.

"I think this guy’s got more of a chance. He can fight. They call him the Scouse Mexican – he fights like a Mexican.

"I think what he bring to the table creates fireworks, we’re going to see a huge upset.

"Be prepared for a huge shock in September, we’re going to see something special."
