Under current rules, clubs are expected to give “full, complete and prompt assistance” to any Premier League inquiry, but should this fail to happen the league must resort to fines, a tribunal or the Football Association to resolve the problem.
The letter also suggested the league had failed in its obligations to properly discuss the measures through the professional football negotiating and consultative committee (PFNCC), which is made up of representatives of the PFA, EFL, Premier League and FA.
A Premier League statement issued in response to the letter said: “We strongly disagree with the PFA’s views regarding the proposed financial rules and the consultation process we are conducting with our clubs and other stakeholders.
The Premier League has asked its clubs for expanded investigatory powers, including the right to access club premises, as part of new financial rules.
However the powers the league is looking to acquire would be stronger than those proposed for the Independent Regulator for English Football, which must – under the current drafting of the bill – request a warrant from a tribunal or court before taking action.
