Smith, known as ‘Beefy’ to many in his native Liverpool, fights as a world champion for the third time, having successfully seen off challenges from Jimmy Kelly and Predrag Radosevic.
‘Canelo’, however, is a different prospect altogether. The heavy favourite for this fight, you may recall he knocked Amir Khan out cold in Las Vegas four months ago.
The Mexican moves down to 154lbs to meet Smith, having vacated his WBC world middleweight belt to avoid an showdown with Gennady Golovkin in the immediate future.

The fight will take place at the AT&T Stadium in Arlington, Texas on Saturday 17 September.

What are they saying?
Smith: “I'm not stupid. I know on paper I'm the B-side of this fight. Canelo's the big name. It's always Canelo, and it's Mexican Independence Day, so I know that. But I am the champion, and just looking back on that, that is one reason why I hope they'll respect that I'm champion and be fair. If I win the fight, then make sure I get the decision.”
Alvarez: "We have seen footage of Liam Smith, he is a strong fighter and his style of boxing is similar to mine. Both our styles will make a great fight for all the fans on Saturday. He is a hard puncher, connects, comes forward and has good combinations. We know he is dangerous and we are not underestimating him.
"I am preparing for a fighter that comes forward, I am ready for anything. We will show the best fight we can for all the fans on Saturday night."
What are the odds?
Smith by KO: 10/1
Alvarez by KO: 1/2
