Atletico Madrid have been fined 12,000 euros ($13,000) by the Spanish soccer federation due to their supporters singing "Die Griezmann die" at Barcelona forward Antoine Griezmann at a La Liga match between the sides last December.
A statement from the federation's competition committee on Wednesday confirmed the fine for the chanting, following a complaint from La Liga. The referee's report from the game on Dec. 1 did not make any reference to the chanting.
The league's organising body has been cracking down on offensive chanting since a Deportivo La Coruna fan died following violence before a game away to Atletico in 2014.
Griezmann spent five seasons at Atletico before joining Barca in July after the Spanish champions paid the France forward's 120 million-euro release clause.
