Murray looking to 'shock the world'

Martin Murray hopes to "shock the world" by beating Argentine Sergio Martinez on his opponent's home soil in Buenos Aires.

The 30-year-old middleweight from St Helens is trained by former world champion Ricky Hatton and will be looking to upset a vociferous home crowd at Velez Sarsfield's football stadium.

Since beating Kelly Pavlik in 2010, Martinez has successfully defended his WBC middleweight title five times while Murray is unbeaten but will begin the contest as a major underdog.
