Barcelona president Josep Maria Bartomeu said Atletico Madrid do not have evidence to support them in their dispute over Antoine Griezmann's transfer fee.
Griezmann joined Barca on Friday after they activated his €120 million buyout clause, but Atletico believe the two parties agreed terms prior to its reduction on July 1.
Per AS, Bartomeu said:
"I have spoken to them, but I do not think there is any proof, because there is no evidence of anything.
"I understand everyone defends their interests, and I've spoken to [Enrique] Cerezo [Atletico president], but I don't see that the case can evolve in a positive way for them.
