The vision of European Club Association chairman Andrea Agnelli is for a revised 32-team tournament, with four groups of eight, with promotion and relegation to the Europa League and a new third tier only affecting eight of those sides.
A proposal has now been submitted to expand the competition from 32 to 40 or 48 teams, according to the Times.
This was based on comments by league officials who have seen it. This year's semi-finalists Ajax, for example, will still need to go through two qualifying rounds to reach the group stages for next season.More news: Ola Aina set to join Torino on permanent deal
European clubs will urge UEFA to make a huge change to the Champions League, to avoid it becoming a mainly closed competition, the UK Times reports.
A format with 40 or 48 teams would favour not only Europe's wealthiest clubs but also traditional giants, such as Ajax and Celtic, who do not now qualify for the Champions League group stage by winning their domestic leagues. Subsequently, all 20 of England's Premier League teams opposed it. In Spain, only Barcelona and Real Madrid approved it, Germany's Bundesliga rejected it and in France 17 of its 20 top division teams openly came out against the reforms.

The ECA has also tabled more radical changes, with a European competition made up of 128 teams in three divisions.
This would require eight groups of five or six, and though this would necessitate more group games and matchdays, it would still be fewer than that proposed by Agnelli.

UEFA president Aleksander Ceferin has called a meeting on September 11 with the ECA and European Leagues group, which has fiercely opposed the clubs' core idea.
