Madrid "Atletico" sports director Miguel Angel Gil Marin expressed great dissatisfaction with Barcelona's actions in trying to attract forward Antoine Griezmann.
Rumors have spread in the Catalan media that Barcelona has already agreed on personal terms with the French footballer and will buy his 100 million euro contract this summer.
It is believed that Barcelona is negotiating with A. Griezmann behind Atletico's back, and the Catalan club is also openly showing interest in the forward's arrival.
"There has not been a single time when we talked about negotiations with Griezmann. We have no reason to do so," Gil Marin said in an official statement.
"A few months ago, I informed the Barcelona president that Griezmann is not on the list of players for sale. At the same time, I warned him that they are not playing by the rules.
We are very disappointed with Barcelona's behavior. It is hard to believe that the team's leaders, representatives, and players are discussing a future newcomer and his contract when he will soon help us win the Europa League final against Marseille.
We have had enough. We hope that this message will have some benefit and our club's fans can only think about the upcoming final," said the Atletico sports director.
