Manchester City’s owners say they are considering legal action after La Liga president Javier Tebas accused them of “financial doping”.
Tebas, head of Spain’s top flight, said City and French club Paris St-Germain had spent money from outside football and action should be taken to stop it.
City’s summer outlay of £215m was the most by any club in a transfer window.
“Mr Tebas’ statements are ill-informed and in parts pure fiction,” said the City Football Group (CFG).
“As you would expect, Manchester City Football Club and the City Football Group are seeking appropriate legal counsel and will act accordingly on that advice.”
City were taken over by the Abu Dhabi United Group in 2008.
