Teams competing in the Champions League will have to play four extra matches from 2024 as European football chiefs close in on an agreement to revamp the tournament, according to The Times.
A new report claims that European Clubs' Association (ECA) and senior figures at UEFA want to expand the competition, which could cause chaos for England's already-packed football schedule.
Although it has not been confirmed how the four extra matchdays will be squeezed in, it is said that the group stage of the competition will either be changed or another one added before the knockout rounds begin.
The ECA had originally hoped to add 10 extra fixtures to the Champions League in order to increase games played between European football's biggest clubs.
But it is claimed that they are satisfied by the new proposal of four matches, even though it could cause a major problem for Premier League clubs.
The Times report that the Carabao Cup could become a competition exclusively for sides not competing in the top tier of European football as a result.
The controversial plan, which has been consistently opposed by the Premier League, would mean that the finalists of the competition play 17 matches rather 13.
However, the new format is likely to appeal to the likes of Liverpool, Manchester City and the rest of the 'Big Six' as more Champions League fixtures will lead to increased revenues.
There is potential for UEFA to introduce eight groups of six teams rather than four, or six groups of six teams, in order to add the four extra games to the schedule.
An alternative would be to add an extra group stage, potentially with the eight quarter-finallists being split into two groups of four, with the top two progressing to the semi-finals.
