Real Madrid has said it will launch civil and criminal lawsuits against the president of La Liga, Javier Tebas, and the chief of CVC Capital Partners, Javier de Jaime Guijarro over their proposed €2.7bn (£2.3bn) deal.
The Spanish football club also said on Tuesday it would pursue legal action to block approval of the planned deal, which is to be voted on by the 42 teams in the top two divisions.
The league said last week that the deal, called “Boost La Liga”, would strengthen its clubs and give them funds to spend on new infrastructure and modernisation projects as well as increasing how much they could spend on players’ salaries.
But Real and Barcelona have fiercely opposed the deal as it gives the private equity firm CVC a 10% share in the league’s future television rights.
Tebas responded to the statement with a message on Twitter in which he criticised Real president Florentino Pérez for using “threatening methods”.
CVC Capital Partners was not available for immediate comment.
Barcelona president Joan Laporta last week said the deal was like “mortgaging the club’s rights over the next half-century” and said he would reject it, even though the deal would have helped alleviate the Catalan club’s financial problems and allowed it to sign Lionel Messi, who has left Barça, to a new contract.
The Spanish league last week said it was not worried by legal moves from Real Madrid and that legal disputes between the two entities were common.
