After Croatia’s quarterfinal victory over Russia, a video was posted online showing Vida, a former player with Ukrainian club Dynamo Kyiv, saying “Glory to Ukraine!”

Russia’s relations with Ukraine have been fraught since Moscow annexed  Crimea in 2014 and backed pro-Russian separatists in eastern Ukraine.

World football’s governing body FIFA ruled that Vida’s comments were not in keeping with tournament rules about political neutrality.

The booing and whistles rang out each time Vida touched the ball in the semifinal against England, starting about 30 minutes into the first half.

It did not appear to be coming from sections of the stadium where England supporters were concentrated. There were significant numbers of Russians in the stadium.

FIFA hit Ognjen Vukojević, a member of Croatia’s coaching staff who appeared in the video with Vida, with a 15,000-Swiss-franc (RM61,000) fine. Vukojević was fired from his role with the national team.

Vida said his comments in the video were not intended to convey any political message.

But his reference to Ukraine angered Russian football fans and politicians. Some Russians said they had originally planned to support Croatia in the semifinals after their own team were knocked out, but that they had changed their minds after learning of Vida’s remarks.
