Furious LaLiga chief Javier Tebas has accused the owners of Manchester United and Liverpool of plotting with FIFA to 'destroy' football.
United's American owner Joel Glazer and Liverpool's John W Henry have been involved in drawing up plans for a European Super League worth £4.6billion.
The project initially had the backing of FIFA and would have been a rival to UEFA's Champions League but world football's governing body has since distanced itself from the plans.
Spanish giants Real Madrid and Barcelona would likely be among the teams breaking away if the European Super League ever happened with Real president Florentino Perez also involved in the project.
