La Liga has intensified its battle against Manchester City and Paris St. Germain by protesting to Uefa about what it sees as Financial Fair Play transgressions.

La Liga president Javier Tebas has frequently denounced the pair, whom he describes to as "state clubs," in addition to fiercely condemning PSG for the new multi-million pound contract the French club awarded star forward Kylian Mbappe in May.

Since then, Premier League City has made official the £51.2 million purchase of Erling Haaland from Borussia Dortmund.

Real Madrid was intrigued by both players.

"La Liga understands that the irregular financing of these clubs is carried out, either through direct money injections or through sponsorship and other contracts that do not correspond to market conditions or make economic sense," said La Liga.

"La Liga considers that these practices alter the ecosystem and the sustainability of football, harm all European clubs and leagues, and only serve to artificially inflate the market, with money not generated in football itself."

Although La Liga claims it maintains the ability to extend these complaints, the one against PSG was filed last week, and the one against City in April.

When Tebas has complained in the past, City and PSG have both vehemently defended themselves.

A two-year Champions League suspension issued on City by Uefa for Financial Fair Play violations was overturned by the Court of Arbitration for Sport in July 2020.

New financial rules established by Uefa in April doubled the amount clubs might lose over a three-year period from 30 million to 60 million euros, with certain clubs permitted an additional 10 million euros provided they are in "excellent financial condition."

Last month Tebas said La Liga would take legal action against PSG after Mbappe snubbed a move to Real Madrid.

The France international instead renewed his contract with PSG until 2025, and Tebas and La Liga said the contract extension "attacks the economic stability" of European football.
