All 20 Premier League clubs said they opposed reform proposals over the UEFA Champions League via a statement posted on the top English soccer league's official website on Friday.

"All 20 Premier League clubs today discussed their significant concerns regarding reported proposals for changing the format and qualification criteria for UEFA club competitions from season 2024/25. All clubs unanimously agreed it is inappropriate for European football bodies to create plans that would alter the structures, calendar and competitiveness of the domestic game and will work together to protect the Premier League," said Premier League in the statement.

According to the Wall Street Journal, the UEFA and the European Clubs Association (ECA) planned to discuss radical changes to the Champions League. Then Bild reported that Andrea Agnelli, president of Serie A's Juventus and current president of the ECA, wanted to combine all European competitions into a coherent league system and shared his plan.

Generally, the Champions League will switch from today's eight groups of four teams to four groups of eight teams. The top four in each group will make it to the elimination stage, while the top six in each group will be automatically qualified for next season's Champions League, and the bottom two in each group will be relegated into a second tier, which should be the Europa League.

This plan is reportedly to be implemented in 2024 when the next Champions League cycle comes to an end. It was "the introduction of a European Super League via the back door," said Bild.

Georg Pangl, general secretary of the Association of European Professional Football Leagues did not like the plan. "If these reports are true, and I have no doubt they are, then the Champions League would become a closed circle from 2024. It would be more or less the same 32 top clubs each year, without the champions of the national leagues getting a chance to qualify. That would be absolutely unacceptable," said Pangl to Bild.

This reform plan, if implemented, will put an end to the era of domestic leagues deciding which clubs will join the Champions League. Moreover, it may also schedule certain games for the weekend, which could further harm Europe's major soccer league's interests.

"In England, football plays an important role in our culture and everyday life. Millions of fans attend matches across the country, with allegiances and local rivalries often passed down through generations. We have a fantastic combination of competitive football and committed fans that we will vigorously defend. The structures of domestic football are determined by leagues and their respective national associations. We will now work with The FA and other leagues to ensure that European football bodies understand the importance of this, and their obligation to maintain the health and sustainability of domestic league football," said Premier League in the statement.
