John Ryder faces the challenge of a lifetime as he attempts to dethrone the great Canelo Alvarez in Mexico tonight. Ryder set up this mammoth career night by beating Zach Parker back in November to collect the vacant WBO interim title at 168lbs, making him mandatory challenger for one of the four titles currently held by Canelo, who bounced back from his shock loss to Dmitry Bivol up at light-heavyweight by settling his long-running rivalry with Gennady Golovkin once and for all in Las Vegas last September. It is sure to be an emotional homecoming for world boxing’s biggest name, and he will be ultra-confident of adding Ryder to his extensive list of vanquished British opponents that already includes Billy Joe Saunders, Callum Smith, Rocky Fielding, Liam Smith, Amir Khan, Ryan Rhodes and Matthew Hatton.
