The Championship has been urged to follow League One and Two clubs in agreeing a salary cap by the chair of the parliamentary committee which last month recommended greater cost controls across the English Football League.

Third and fourth-tier clubs have voted in favour of squad salary caps in a bid to tackle the "profound" financial impact of the coronavirus pandemic.

League One clubs have agreed a £2.5million squad cap, with League Two sides opting for a £1.5m limit. Both caps will be introduced with immediate effect, the EFL said.

It is understood Championship clubs have no plans at this stage to hold a formal vote on a cap, but Julian Knight, the chair of the Digital, Culture, Media and Sport (DCMS) committee says they have to act.

He said: "It seems there is a breaking out of common sense amongst league clubs. For a long time the flawed business model of much of football has been as clear as day but it's taken the biggest financial crisis in English football since the war for some action.

"Let's see if more realism now permeates the Championship, where player wages incredibly outstrip club turnover."

Deloitte reported earlier this year that second-tier clubs had a combined wages-to-turnover ratio of 107 per cent in their 2018/19 accounts, and lost a combined £300m. Rovers’ figure was 134 per cent.

In announcing the League One and Two cap, EFL chief executive David Baldwin said: "The term 'salary cap' is an emotive one, creating the impression of a restrictive measure but we are clear in our view that this is neither the objective nor the likely effect of these changes to EFL regulations.

"The financial impact of Covid-19 will be profound for EFL clubs and the vote will help ensure clubs cannot extend themselves to the point that could cause financial instability."

Players' union the Professional Footballers' Association has expressed concerns about the new regulations, and called on Thursday for further consultation and clarity around the objectives for introducing a cap. It has been approached for comment.

The EFL said the cap did include basic wages, taxes, bonuses, image rights, agents' fees and other fees and expenses paid directly or indirectly to all registered players.

There are a number of exemptions. Players under 21 are understood to be exempt from the cap, as are players whose deals were agreed before the introduction of the cap.

Those players will also be able to extend on the same terms if aged under 24 at the time of renewal.

There would also be a relegated player exemption, if the player's terms were agreed no later than the end of the January transfer window in the season the team were relegated.

There will be a five per cent 'overrun' permitted, with financial penalties imposed on a sliding scale. Beyond five per cent, clubs will be referred to an independent disciplinary commission where sanctions would be imposed if found guilty of a breach.
