FIFA have began probe into Croatia’s celebrations, after they eliminated Russia from the 2018 World Cup on Saturday night.
Croatia defender, Domagoj Vida, is facing possible disciplinary measures for posting a video, dedicating the victory to Ukraine.
Vida scored an extra-time goal and one of their penalties in a 4-3 shootout win over the World Cup hosts in Sochi on Saturday.
The ponytailed 29-year-old shouted “Glory to Ukraine!” in a video posted by former Croatia international, Ognjen Vukojevic shortly after the match.
“Glory to Ukraine!” was a slogan of the former Soviet republic’s pro-EU revolution that toppled a Russian-backed president in 2014.
Some Russian officials are already calling on FIFA to take the toughest measures possible against the Balkan country.
The world football governing body said in a statement: “FIFA is processing the different reports of the said match as well as potential evidence concerning the matter referred to in your message,” a FIFA spokesperson told AFP.
“Until we have evaluated all information available, we cannot comment further.”
Vida later told Russian media that he meant no offence.
“I love Russian people,” Vida was quoted as saying.
“It was just a joke.”
