Bookmakers are predicting a boxing betting bonanza over Anthony Joshua's world heavyweight title showdown with Wladimir Klitschko at Wembley on Saturday night.
The hotly anticipated mega-fight — which will set a new post-war boxing attendance record — is expected to be the second biggest betting bout since Floyd Mayweather and Manny Pacquiao smashed box office records in 2015.
"Big fights like this always attract casual fans and despite no table-throwing and fancy dress antics in the build-up, there's no doubt this one has caught the imagination of the British public," said a Paddy Power spokesman.
"We're expecting over £20m to be staked across the industry — putting it just behind the Mayweather versus Pacquiao fight in 2015."
A not insignificant chunk of that could come from Klitshcko's previous opponent Tyson Fury, who told his Twitter followers he would bet £100,000 on his vanquished foe to topple Joshua.
Around 90,000 fans are expected to fill Wembley to watch 27-year-old Joshua defend his IBF title and compete for a WBA "super" belt against the 41-year-old Klitschko.
As well as the bumper-crowd, the fight is forecast to draw in record pay-per-view sales for a British fight.
