LaLiga president Javier Tebas has accused Chelsea of "cheating" in the transfer market.
Enzo Fernandez, Mykhaylo Mudryk and Benoit Badiashile all signed long-term contracts until either 2030 or 2031. Although completely legal, the ploy is a way of spreading the cost of a player across a longer period and therefore passing FFP regulations.
Chelsea's tactic has annoyed La Liga, who themselves have imposed strict financial limits on their clubs. President Tebas is unhappy with the Blues and has incredibly accused them of 'cheating'.
"Chelsea are clearly cheating by signing players on eight or nine-year contracts," Tebas said at a press conference on Thursday.
UEFA have already started plans to prevent clubs from handing huge contracts to new signings. Chelsea boss Graham Potter admitted in January that the huge deals for the young players were risks.
"There is no guarantee anywhere, no magic formula that says this is going to work and this is how we see the future," Potter told reporters.
"The players we identified are young, they've got quality. With Mudryk and Joao (Felix) coming on loan there's a certain type of player in terms of age. They are starting their careers so they are ambitious ... they're here to win and compete.
"Those are the upsides but is there a life without risk? No. Whatever you do there is risk and there is a chance it might not work. You have to understand that and the consequences."
