A Premier League statement added: "The Premier League is proud to run a competitive and compelling football competition that has made it the most widely watched league in the world. Our success has enabled us to make an unrivalled financial contribution to the domestic football pyramid.
"A European Super League will undermine the appeal of the whole game, and have a deeply damaging impact on the immediate and future prospects of the Premier League and its member clubs, and all those in football who rely on our funding and solidarity to prosper.
“We will work with fans, The FA, EFL, PFA and LMA, as well as other stakeholders, at home and abroad, to defend the integrity and future prospects of English football in the best interests of the game.”
To add to the pressure building on the rebels, Premier League chief exec Richard Masters wrote to all 20 clubs yesterday reminding them of “Rule L9,” which forbids teams playing in non-sanctioned events without permission.
“I cannot envisage any scenario where such permission would be granted,” he wrote. “It is the duty of the Premier League Board to defend the integrity and future prospects of the League as a whole, and we will have no choice but to do everything we can to protect and maintain both.”
