LaLiga president Javier Tebas has questioned whether Atletico Madrid can sign Chelsea striker Alvaro Morata.
Tebas believes Atletico's budget won't stretch to cover Morata's demands.
He told AS: "They're very limited; they would have to get rid of someone. I do not know exactly because that is what is needed for the economic controls."
Tebas was also asked about Real Madrid buying PSG star Kylian Mbappe or Neymar.
He added: "Either one of the two. Or the two. I do not know if Florentino (Perez) wants to sign one of the two. We have worked hard on the brand and it is above the players because we have taken advantage of the synergy of the clubs.
"What we do not know is how much more we would be favoured by them being here."
