"FIFA is looking into the matter. For the time being we have no further comment," FIFA said when asked if they plan to open an investigation into the matter.

On Saturday night, a video was posted online of Vida chanting "Glory to Ukraine!" after Croatia beat Russia on penalties in the World Cup quarter-finals.

Both Vida and the Croatian Football Federation later apologised for his statement.

The 29-year-old Besiktas player avoided a ban and will be eligible to play against England in the last four.

Croatia's coaching assistant Ognjen Vukojevic said "This is a victory for Dynamo [Kiev] and Ukraine" in the same video and was later suspended from his duties at the World Cup by the Croatian Football Federation, while the FIFA Disciplinary Committee fined him $20,135 for unsporting behavior.

Croatia will face 1966 champions England in the World Cup semi-finals in Moscow on Thursday morning at 4:00am AEST.
