After his country's sensational passage to the World Cup final with a win over England, Croatia defender Domagoj Vida apologised again on Thursday for the pro-Ukrainian celebrations that followed a win over hosts Russia in a previous round.

"That was a mistake, and you have to learn from your mistakes," Vida told Russian television after the 2-1 extra-time win over England.

Vida initially received no reaction when he was on the ball, but the Russians in Moscow's Luzhniki Stadium appeared suddenly to remember that he had twice appeared in videos, posted on social media, in which he'd said: "Glory to Ukraine!"

The treatment hadn't bothered him, Vida told broadcaster Russia-24.

Both videos appear to have been recorded shortly after Croatia's win on penalties over Russia in Sochi on Saturday.

FIFA fined Croatian team official Ognjen Vukojevic 15,000 Swiss francs (15,000 dollars) for unsporting behaviour for posting the first video.

Vukojevic, a former Croatian international, was a team observer and had played with Vida at Dynamo Kiev. Both he and Vida apologized, with Vida received a warning from FIFA, while Vukojevic was relieved of his duties by the Croatian football federation (HNS) and had his accreditation revoked.

The federation apologized to Russia and FIFA for the first video and Vida, who left Kiev in 2017, told Russian portal the video had "nothing to do with politics" but was a joke for friends.

Russia currently faces international sanctions over the country's role in the Ukraine conflict. The sanctions were first adopted in July 2014 following Russia's annexation of Ukraine's Crimean peninsula and its support for separatists in eastern Ukraine.
