The European Super League (ESL), officially The Super League, was a proposed seasonal football competition for club teams in Europe. Initially, the league was supposed to include 20 teams, with 12 of them being founding members of the competition.
The formation of the ESL led to widespread condemnation from UEFA, The Football Association and Premier League of England, the Italian Football Federation and Lega Serie A of Italy, and the Royal Spanish Football Federation and La Liga of Spain. All governing bodies issued a joint statement declaring their intention to prevent the new competition proceeding any further, with UEFA warning that any clubs involved in the Super League would be banned from all other domestic, European and world football competitions,[62] and that players from the clubs involved would also be banned from representing their national teams in international matches.[62][63] In addition, the French Football Federation and Ligue de Football Professionnel of France, the German Football Association and Deutsche Fußball Liga of Germany, as well as the Russian Premier League and Russian Football Union released similar statements opposing the proposal.[64][65][66][67]
UEFA began immediately looking into making further reforms to the Champions League in a €6 billion effort to prevent the proposal moving forward.[68] The Premier League and the Football Association released a statement “unanimously and vigorously” opposing the breakaway league but ruled out barring the six breakaway clubs from domestic competitions and preferred to not take legal action against them.[69]
Numerous politicians expressed their opposition to the proposals across Europe, the most prominent coming from the British government, with the objections to the ESL uniting political parties completely behind its prevention. British Prime Minister Boris Johnson called the proposals “very damaging for football” and vowed to ensure that it “doesn’t go ahead in the way that it’s currently being proposed”,[93] a position which was supported by Leader of the Opposition Keir Starmer.[94] In addition, the Culture Secretary Oliver Dowden said in a statement to the House of Commons that “this move goes against the very spirit of the game”, and pledged to do “whatever it takes” to stop English clubs from joining.[95]
So that says that it’s a response to the European Super League.
