Billy Joe Saunders Says He's Most Determined Fighter Canelo Alvarez Has Ever Faced

On the eve of the biggest fight of his career, Billy Joe Saunders delivered a message to Saul "Canelo" Alvarez. 

Speaking to reporters during Friday's media session, Saunders said Canelo has "never faced a man with so much determination."

Canelo didn't sound too concerned about Saunders when he got the chance to respond:

Saunders enters Saturday's matchup with a perfect 30-0 record in his career. The English star most recently defeated Martin Murray by unanimous decision in December to retain the WBO super middleweight championship. 

Alvarez will be a step up in competition for Saunders. The 30-year-old is 55-1-2 in his storied career and is currently riding a 14-fight unbeaten streak since losing to Floyd Mayweather Jr. in September 2013. 

The winner of the bout will be the unified super middleweight champion.
