This lawsuit was initially filed by three ex-fighters in 2014 and now looks likely to be heading to trial in April.

The documents revealed that McGregor made £2.1million for his fight vs Chad Mendes in July 2015.

He then made £3.7million for his title fight vs Jose Aldo later that year.

In 2016, McGregor earned £4.5million when he fought Nate Diaz.

And he made £4.6million for the rematch, despite suffering defeat in the first clash.

Finally it was revealed that McGregor took home £5.5million for his fight vs Eddie Alvarez.

Paul, who has earned tens of millions from his boxing career, tweeted in reaction: “This is f***ing hilarious and sad at the same time.”

He has since deleted the tweet.

However, Paul has since also taken aim at Nate Diaz, who he beat in a boxing match earlier this year.

He tweeted: “Nate Diaz made more in one boxing match than he did fighting Conor McGregor twice in MMA. No wonder that boy begging for a boxing rematch.”
