Leeds United CEO Angus Kinnear has heavily criticised the "self-proclaimed big six" in the Premier League for their involvement in a breakaway European competition, branding the "deeply cynical" plan a betrayal of every true football supporter.
Arsenal, Chelsea, Liverpool, Manchester City, Manchester United and Tottenham were all part of a 12-club group that launched the Super League last Sunday.
The proposal included the agreement that the six English clubs, as well as fellow founding members Atletico Madrid, Barcelona, Inter, Juventus, Milan and Real Madrid, would qualify each year for the competition, regardless of performances in their domestic leagues.
However, a widespread backlash led to the collapse of the competition inside 48 hours of the initial announcement. The Premier League contingent all withdrew on Tuesday, though UEFA president Aleksander Ceferin has made clear there will still be consequences for getting involved.
Ahead of hosting Manchester United at Elland Road on Sunday, Kinnear lambasted Leeds' domestic rivals in his programme notes.
"The fact that the whole Leeds fan-base has been united by the brilliantly impassioned words of Gary Neville illustrates how desperate the plight of European football became this week," Kinnear wrote.
"A fortnight ago we left the Etihad with an instinct that Manchester City didn't take well to being humbled by lowly Leeds United, but we could never have predicted that it would be the catalyst for them creating their own league where they would never have to be inconvenienced with the spectre of on-pitch failure again.
"The audacity of a resurgent Leeds United, an ambitious Aston Villa, a brilliantly managed Leicester City, a Champions League-bound West Ham United and an Everton with bold stadium plans have clearly overwhelmed the self-proclaimed 'big six'.
"The timing of their plan combined with the turmoil of a global pandemic was not coincidental, it was deeply cynical, and the clandestine plotting of fellow Premier League shareholders made it all the more seditious.
"Whether the collective intent was a genuine move to breakaway or the act of playground bullies seeking negotiating leverage at European and domestic level by threatening to take their ball home is irrelevant. The result was a betrayal of every true football supporter. However, this astonishing ingordigiousness has been the unexpected catalyst of creating a furious unity across nations, leagues, players, owners and fans.
"I was proud to see Leeds United and Liverpool supporters stand shoulder to shoulder in protest before a game which once again showed we are already in a Super League and making it all the more bizarre that, in the world envisioned by Liverpool's ownership, the same fixture would have been a meaningless dead rubber."
Fans protested outside Elland Road on Monday ahead of Leeds' home fixture with Liverpool – a game that finished 1-1 after Diego Llorente dented the visitors' top-four hopes with a late equaliser.
The hosts had warmed up prior to the game wearing shirts that read "Earn it" – in reference to the Reds' bid to qualify for the Champions League – and "Football is for the fans". There was also a sign saying the same stationed behind one of the goals inside the stadium.
