The two middleweight champions enter the ring on May 8, with Alvarez being fancied to put an end the Brit’s unbeaten professional record.
Saunders is underdog for the bout being held at the AT&T Stadium, with bookmakers pricing him at 4/1 to beat the Mexican.

And speaking ahead of the fight on his Hotboxin’ podcast, Tyson was quick to quip Saunders’ outside chances of an upset.
He said: ‘He’s knocked out right now, he’s knocked out already, I swear, he’s knocked out.’
WBO Super Middleweight champion Saunders faces the toughest test of his career against Alvarez – who has lost just one of his 58 fights.
His only loss came against the legendary Floyd Mayweather back in 2013, but he has still gone on to hold belt in four different weight classes.
Not everyone is backing the 30-year-old Mexican in the headline bout, however, with heavyweight champion Tyson Fury backing his friend and training partner.

‘Billy Joe Saunders is 100% mentally in the right place,’ he wrote on his Instagram
‘He knows what he has to do and he will do it, he will rise up [to the to] and claim greatness.
‘I was wrote off many times in the past and have always come through.
‘WE are cut from the same cloth, same breed of animals.
‘Canelo has fought them all but never a Fighting Gypsy, we are a different breed of animal to anything he has come across before.
‘#YESHEWILL. World domination with the help of God.’
