The European Leagues has said plans to revamp the Champions League should be started from scratch, as the current proposals only benefit "a few rich and dominant clubs".
"The concept being discussed by the European Clubs Association (ECA) would have unacceptable consequences for the national leagues in Europe and, therefore, it shouldn't be implemented in this way" said Bundesliga president Christian Seifert.
The French Football League (LFP) and the German Football League (DFL) have signalled their opposition to proposed Champions League changes. France has nine clubs in the powerful organization.
The top 24 teams would keep their places for the next season, ending the tradition that qualifying for European competition is achieved via national leagues.
Manchester United executive vice-chairman Ed Woodward believes the radical changes being explored to the format of continental club competitions are "partly driven by domestic leagues across Europe not necessarily thriving".
The plans have been heavily criticised by a number of league officials, including the Premier League and La Liga, as they are seen in some quarters as an attempt to ring-fence the competition to favour the continent's biggest sides.
"UEFA must come to an agreement with the European Leagues and the other stakeholders to safeguard the interests of all professional football clubs in Europe".
"French football is anxious about the sporting and economic consequences of the current project for the national championships", said the LFP.
French football federation president Noel Le Graet attended the meeting and presented an alternative proposal to overhaul Europe's top tournament. Currently, Champions League places can only be earned by a high finish in a domestic league or by winning the competition or the second-tier Europa League title.
Le Graet should represent France on Friday at a UEFA summit of 55 member federations in Budapest, Hungary.
Fearing a loss of TV revenues for French football authorities and clubs, and an overcrowded match calendar, Le Graet said a closed-off Champions League would undermine the country's domestic championship.
But on Thursday, European Leagues said the proposals "damages the leagues". "If it is validated, we will present it to UEFA in the coming days".
Several league representatives who were present at a meeting with UEFA last week have said they were presented with a proposal to create a three-tier European league with promotion and relegation between each division.
