The PFA offer a strong response to the new salary caps facing Sunderland and their League One rivals

Third tier clubs today backed plans to introduce a £2.5million spending limit which will be implemented with immediate effect.

Sunderland were strongly against the plans, but the plans were passed after 16 clubs voted in favour. Seven clubs voted down the plans, while one club abstained.

But the PFA – who hit out at the plans on the eve of the League One vote – have expressed their disappointment at the outcome and are now seeking to open a period of arbitration with the EFL.

"We are disappointed at the outcome of today's votes," the union said in a statement.

"The EFL has ignored its legal obligation to consult with the PFA and the Professional Football Negotiating and Consultative Committee (PFNCC).

"As such, the legal advice we have received is clear that the salary cap envisaged by the EFL would be unlawful and unenforceable.

"The PFA has already served its Notice of Arbitration on the EFL and until such time that arbitration is determined one way or another the new regulations should have no effect.

"While we share the league's commitment to protecting the long-term sustainability of the leagues, the salary cap proposals voted on today have been rushed through without the proper consideration or consultation."
