European football's governing body, UEFA, are reportedly "monitoring" the situation with Russia and Ukraine's military crisis, with a possible view to a switch of this year's Champions League final location.
The final of Europe's most prestigious club competition is due to be played in Russia's second-largest city - at the Gazprom Arena in St. Petersburg - on 28th May.
But UEFA has found itself under increasing pressure to move that choice of venue after Russia's president, Vladimir Putin, announced a decision to send troops into Ukraine's eastern Donbas region.
