Tyson Fury has posted before and after pictures via Instagram of Billy Joe Saunders, highlighting the colossal effort his close friend has made throughout his latest training camp.

The Hertfordshire-born Southpaw will aim to become a two-weight world champion this Saturday night when he faces Serbian-born German Shefat Isufi for the vacant WBO super middleweight title at Stevenage’s football ground, the Lamex Stadium.

Isufi (27-3-2) is currently on a 10-win streak, and will look to put the first blemish on Saunders’ (27-0) undefeated record.

Last year, the 29-year-old vacated his WBO middleweight title after testing positive for Oxilofrine, a substance banned in Massachusetts where his title bout against Demetrius Andrade was scheduled to take place.

Saunders’ wallet also took a substantial hit in the last 18 months after some immature behaviour in his personal life arose via social media. He was fined by the British Boxing Board of Control to the tune of £100k.

A chance for redemption awaits this weekend for Saunders and ‘The Gypsy King’ wanted to underline the extraordinary progress his close friend has made over the past three months with an uplifting Instagram post.

“@saundersbillyjoe just want to say how proud I am to know a legend like you! You have become the man I always thought you would be! Soon to be 2 weight 2x world champion.”

Fury will make his ESPN debut on June 15 when he takes on unheralded German heavyweight Tom Schwarz in Las Vegas.

The giant Mancunian views the clash as simply a warm-up for a potential blockbuster at the end of the year.

Last week, WBC president Mauricio Sulaiman revealed that Fury has been instructed to face Dillian Whyte to decide Deontay Wilder’s next mandatory challenger.

Should the mouthwatering all-British fight of Fury v Whyte go ahead, it could be ‘The Gypsy King’s’ penultimate chance to thrill the boxing world after the 30-year-old hinted at an early retirement from the sport after his next three fights.
