Barnsley have hit out at the English Football League in a statement that appears to take aim at both Sheffield Wednesday and Derby County.
The Tykes managed to avoid relegation by one point but the club have called for a 'change to the system' and have slammed a 'blatant disregard for sporting integrity' in the second tier.
Barnsley have been one of the clubs most vocal when it comes to the recent legal cases plaguing the Championship, with Wednesday and Derby both charged by the EFL, while Wigan Athletic have entered administration.
The Owls and Derby have both been charged with financial misconduct in relation to the sale and leasing back of their stadiums, accusations which the clubs refute.
In a statement, Barnsley slammed Leeds United's former Championship rivals by saying: "What Barnsley Football Club cannot accept is the blatant disregard for sporting/competitive integrity and the lack of governance in our division.
"Clubs were charged with breaching rules surrounding Financial Fair Play and harming the EFL and its members. One ownership group, (which was approved by the EFL), failed in their duty to provide the requisite support to their respective Championship organisation.
"One other ownership group completed a takeover and provided funding to a Club without ever being approved by the EFL to become owners of that Club. Another competitor has yet to pay a transfer fee to Barnsley Football Club that was due in August of 2019. Several clubs have been delinquent in payment to contracted players.
"We ask, where is the competitive balance? Our Club, on a substantially smaller budget, has paid every professional player under contract 100% of their wages this season, one of the few Sky Bet Championship clubs to do so.
"It is clear that there has to be a change to the system. Just as our coaching staff, players, Club employees, and supporters have fought this season, so too will your Club continue the fight by all means necessary."
