LaLiga president Javier Tebas won't rule out blocking Antoine Griezmann's move to Barcelona.
With Atletico Madrid having complained about the forward's move to Barcelona, claiming that a deal was organised before his release clause fell to 120 million euros on July 1, LaLiga are currently reviewing the situation and they could block the player's participation in the league.
Tebas told Radio Marca: "Atletico Madrid sent a document that questions whether we should give Barcelona a license for Griezmann.
"It is possible to block a player's registration.
"We are currently working to resolve the situation."
