Manchester United and Manchester City are united in opposing Liverpool's plan to go it alone over the next television deal.
Liverpool managing director Ian Ayre said the bigger clubs should get a greater share of the £1.4billion overseas TV cash - currently shared equally between all 20 clubs.
City chief communications office Vicky Kloss said: "The subject has never been up for debate either inside the club or externally.
"We are well aware of the benefits of the collective selling of Premier League television rights."
United have always been a supporter of collective selling and chief executive David Gill told a Parliamentary committee earlier this year: "The collective selling of the television rights has clearly been a success and it has made things more competitive."
