Croatia defender Domagoj Vida has apologised for his pro-Ukrainian comments after the embattled player was booed and whistled at during his side's 2-1 win over England in the World Cup semi-finals.
"I know that I've made a mistake. I want to once again apologise to the Russian people. I didn't think about it and please forgive me, it's life. You should learn from your mistakes," Vida told the Russia-24 news channel.
Two separate videos of Vida saying "Glory to Ukraine!" were posted online after Croatia beat hosts Russia on penalties in the quarter-finals.
The 29-year-old Besiktas player was handed a warning by the FIFA Disciplinary Committee for his statement but avoided a ban and started for Croatia as they reached the final for the first time.
Croatia, who claimed the third place at the 1998 FIFA World Cup, will take the winners of that tournament, France, in the final, which will be played at Moscow's Luzhniki Stadium on Monday morning (AEST).
