Jake Paul has urged Conor McGregor to pay up and make Katie Taylor's Croke Park dream happen.
McGregor has openly said he would foot the bill for the Croke Park fight with promoters saying the cost of hosting the bout at GAA HQ is too expensive.
Katie Taylor's promoter Eddie Hearn flew into Dublin to meet with McGregor but the May 20 fight looks set to take place at 3Arena.
