MADRID (Reuters) - Barcelona were fined just 300 euros ($ 329) on Thursday for breaching the rules during contact with former Atletico Madrid striker Antoine Griezmann.

Barcelona signed Griezmann in return for the penalty clause in his 120-million-euro contract with Atletico last July, but was convicted of negotiating with the French striker without Atletico's approval.

Atletico demanded an extra 80 million euros, noting that this is the difference between the initial value of Griezmann's contract clause and the new value of the penalty clause.

The Spanish federation acquitted Griezmann of any responsibility for this and said he could not prove that Griezmann had signed a contract with Barcelona while playing or at Atletico Madrid.

The federation noted that negotiations between Barcelona and the player began in May, after Griezmann told Atletico his intention to leave, and noted that the laws allow Atletico to act as long as the player told them his intention to leave, and Atletico had a chance but did not take advantage of them.

"The penalty will not prevent Barcelona or any other club from repeating the same situation in the future, especially since there are rules, but this is not sufficient reason for the committee to impose any other sanctions such as closing the stadium because such sanctions are intended for other violations."

It is noteworthy that Griezmann participated this season with Barcelona in seven games in all competitions, scoring three goals and making two goals.
