Sergey Kovalev Anthony Yarde faces the toughest test of his unbeaten fight career as he heads into Russia's industrial heartland next weekend in a bold bid to dethrone Sergey Kovalev from the World Boxing Organisation light heavyweight crown.
Kovalev defends the title he first won way back in from Nathan Cleverly in Cardiff, in his hometown of Chelyabinsk, where his father was a welder and his mother used to drive a forklift truck. Brought up in old Soviet Russia, in an area where much of the population are blue collar workers, and where the city was once dubbed 'Tankograd' due to the manufacture, decades ago, of T tanks and Katyusha rocket launchers, Kovalev has found riches fighting in the United States.
Times have changed, but there is steel running through the heart and will of year-old Kovalev, whose long career features one draw and three defeats, twice by the brilliance of the now retired American standout Andre Ward.
But there is a sense that Hackney's Yarde will need a touch of genius, more than simply the power that has brought him 17 knockouts from 18 fights to claim what would rank as an outstanding scalp in his first world title challenge.

He has been open about part of his desire to better his wider family's standing in life, having brought his parents to the USA.
Prior to the Ward defeats, he had claimed three of the four light-heavyweight belts.
Indeed, Kovalev was the man to make a slumbering light-heavyweight division 'live' in the last five years. Yarde is certainly up for the challenge, and has shown his determination in taking this step up against a formidable champion in his own back yard.
The year-old Londoner - who has fought 51 rounds to Kovalev's as a professional - is predicting a knockout victory, and is prepared to go into the trenches. Paul Young has a beautiful song, 'Wherever I lay my hat, that's my home.
The tractor days are gone. Yarde has excellent fundamentals, but must now apply them for the first time at an elite level, against an accomplished opponent, who is competing in his 16th world title contest.
The Briton will certainly never been hit as hard, and experience may be the key factor.
