The Champions League could be replaced by a rival tournament backed by a Chinese billionaire
Javier Tebas, president of Spain's two professional football leagues, said there was a "greater opportunity to generate greater revenue" with a tournament backed by the richest man in China.
Billionaire Wang Jianlin's conglomerate, Dalian Wanda, is working on proposals to create a competition heavily favouring Europe's 'Big Five' leagues - England, Spain, Italy, Germany and France.
Football chiefs in Spain are increasingly worried that huge domestic broadcasting deals for the English and German leagues are giving their teams a competitive advantage, and see revenue from European competitions as a means of gaining it back.
Tebas said that he had been attracted to Wanda's proposals since Uefa announced plans to shake up its Champions League competition "without seriously consulting - in detail - their broader reform plans with the other national leagues."
Football-mad China has spent billions of pounds buying stakes in European football clubs in the past year, since President Xi Jinping announced his intention to turn China into a "great sports nation" capable of winning the football world cup.
Financial dominance over European football - and the huge broadcasting revenues it brings - is another aim.
Marco Bogarelli, strategic director of Wanda, said in July that the group are also in talks with the English Premier League, Germany Bundesliga and French Ligue 1.
