The sides want a bigger share of the new deal which is due to begin next season

Leeds United, Aston Villa and Derby County are among 15 Championship clubs at war with the EFL over a planned new TV deal.

A five-year deal with Sky was due to be signed off last month, worth £119 million compared to the £90m valuation of the current contract.

The new TV deal is set to begin next season

League One and League Two clubs back the new deal, but a host of second tier sides refused to put pen to paper.

And, according to The Sun, when a meeting of all 24 clubs was held, 15 of the biggest sides threatened to breakaway from the EFL unless they were given a better deal.

Leeds, Villa and Derby are said to be among those disappointed at the new deal only earning Championship clubs £2.95million each, with a further £17.7million in appearance fees shared.

The current deal sees Championship sides earn £2.3million each.

According to the report, the clubs have been given until next week to reconsider their position, with some believing they should earn as much as double the contracted amount.

Sky currently show 148 live matches per season, with the new deal increasing that number to 183. They also have rights for play-off matches and finals, and have started to show games via their red button service.
