The Blaugrana were reprimanded by the Rojiblancos in a statement this week, but they have acted similarly in the past and can have few complaints
Atletico Madrid are furious with Barcelona. In the midst of their preparations for next Wednesday's Europa League final against Marseille in Lyon, the Rojiblancos have seen the transfer talk surrounding Antoine Griezmann escalate.
The France forward scored in the first leg of the Europa League semi-final tie against Arsenal and Atleti are now within 90 minutes of a first trophy since winning the Spanish Supercopa in 2014.
But it could also be a farewell for Griezmann, although not if Atletico can help it.
