Anthony Joshua is set to pocket the biggest ever pay day for a British boxer, a whooping $85 million, when he takes on Andy Ruiz Jr in Saudi Arabia on Saturday night.

Andy Ruiz Jnr will go home with $13million even if he wins or loses the bout. Anthony Joshua will attempt to regain his WBA, IBF and WBO Heavyweight titles he lost to Ruiz Jr back in June at Madison Square Garden. The Mexican boxer defeated Joshua in the seventh-round to hand British/Nigerian boxer his first professional loss.

Joshua was keen to play down the size of his earnings, saying: "When you look at it, out of every hundred quid, a lot goes to the taxman and a lot to the trainers and the team.

"Before you know it, what you're left with in reality is about 30 to 40 per cent.
