A breakaway league would spell the end of the Champions League and have a huge impact on the Premier League.

The English competition currently enjoys a TV deal which guarantees £100 million per club for the next three years. The departure of the biggest clubs would see that revenue severely diminish, impacting the remaining clubs as well as having a knock-on effect on the whole league.

Uefa has been under increasing pressure from the European Club Association to reform the continent's top club competition to ensure teams with the greatest TV appeal have a guaranteed place.

Uefa said in a statement: “Uefa constantly reviews the format of its competitions in close consultation with stakeholders, including the European Club Association. There are no concrete proposals on the table at this stage as we have just begun a new three-year cycle (2015-18) for club competitions. There is therefore no further comment to be made at this stage.”
