Ex-Genoa coach Andriy Shevchenko calls for peace after Russia staged an invasion of Ukraine, while Poland, the Czech Republic and Sweden released a joint statement refusing to play World Cup play-offs in Moscow.
There are fears Russia could completely annex Ukraine within days, as tanks are already reported to be within 25 miles of the capital Kiev.
There are many Ukrainians connected to Italian football, probably none more famous than former Milan striker Shevchenko, who until last month was the coach of Serie A side Genoa.
“In the early hours a full scale war was initiated by Russia. My people and my family are under attack,” he wrote on social media.
“Ukraine and it’s population want peace and territorial integrity. Please I ask you to support our country and call the Russian government to stop their aggression and violation of international law. We only want peace. War is not the answer.”
Meanwhile, the Polish, Swedish and Czech federations released an unprecedented joint statement announcing they will not play against Russia in Moscow for the 2022 World Cup play-offs.
Poland are due to face Russia in Moscow next month, with the winners going on to face either Sweden or the Czech Republic.
UEFA are already considering whether to strip Saint-Petersburg of the Champions League Final in May, with London a probable alternative venue.
Former Roma coach Paulo Fonseca and current manager of Ukrainian side Shakhtar Donetsk are still in Kiev.
