Former Barcelona and Atletico Madrid striker Julio Salinas supports Barca in the Antoine Griezmann case.
Atletico have reported Barcelona to FIFA for unsettling the Frenchman.
"It was known since last year when [Griezmann] renewed for Atletico with a clause of 200 million euros that he was leaving," Salinas told MARCA.
"And what have Atletico done with Vitolo?
"They say that in the market you can only speak in January with players whose contracts end in June and you can't talk with those whose finish within three years? That's what the release clauses are for.
"He is a player of Atletico until June 30 and it's another matter if he leaves or not.
"Nobody will be surprised if Griezmann goes to Barcelona, as it's the most normal thing in the world."
