Atletico Madrid have reported Barcelona to FIFA over an illegal approach to Antoine Griezmann.

Griezmann signed a new contract with Atleti through 2021 last summer amidst interest from Manchester United.

“Atlético Madrid have reported Barcelona for repeated contact with Griezmann and his people, contact which we are aware of,” a spokesman for Atlético told Mundo Deportivo on Tuesday. “He is a player with a contract with Atletico Madrid and a long contract at that.”

Griezmann has a release clause in his contract set at €100 million (£88.4 million) but Barcelona have been linked with a January approach.
