High level talks over controversial changes to the structure of the Champions League have been postponed by President Aleksandr Ceferin.
Scottish clubs have been watching high-powered discussions closely with a number of radical changes to the Champions League and Europa League having been mooted in recent months.
Premiership sides fear being further sidelined in European tournaments as the continents' elite clubs push for a European Super League.
Celtic were faced with four rounds of qualifying before the lucrative group stage of this year's competition - with the Scottish champions falling at the third hurdle this week.
In contrast 'superpowers' such as England see four clubs qualify straight into the group stage.
Worryingly for Scottish clubs fearing being pushed further out into the cold, one of the plans presented by UEFA would see 24 of the 32 teams in the Champions League group stage keep their place in the competition for the following year.
Parties have been debating a potential restructure of Europe's elite competitions for several months and were due to meet UEFA President Aleksandr Ceferin on September 11.
However, talks involving Ceferin, European Club Association (ECA) chairman Andrea Agnelli and European Leagues president Lars-Christer Olsson have now been postponed, with clubs still arguing over the possibility of a radical overhaul of the competition.
In a letter obtained by AP, the UEFA chief wrote to Agnelli and Olsson: “I have decided to postpone the meeting.
“I will send a new invitation as soon as I think that we are ready for a meaningful discussion.
“We are currently in the process of gathering feedback from our national associations.
“And I feel — more generally — that a new discussion now would be premature as we are analyzing feedback and proposals coming from different parties.”
The letter was sent out a day before the ECA board, led by Agnelli, privately meets in Liverpool to discuss ideas for an overhaul of Europe's club competitions from 2024.
The Juventus chairman has received criticism for supporting a largely closed Champions League and has seen his main idea of restricting access to the competition strongly opposed by both the European Leagues group and a number of ECA member clubs.
Changes could also result in promotion and relegation being introduced in the Europa League as part of a new three-tier structure.
Meanwhile, the ECA has also called for the Champions League's current four-team groups to be doubled so that each contains eight sides.
The Premier League is among those opposing significant changes to the competition's current structure and claims to have backing from all of its teams.
“As you know very well, UEFA deliberately kicked off the review process for the 2024/27 competition cycle much ahead of our regular schedule and we are therefore in no hurry,” Ceferin added in his letter to Agnelli and Olsson.
“We do not, in any case, expect to make a decision this year.”
