UEFA will make a decision on whether or not to move the Champions League final from St.Petersburg on Friday after Russia's invasion of Ukraine.
Calls have been intensifying for European football’s governing body to move this season’s showpiece fixture, currently scheduled to be held at the 68,000-capacity Gazprom Arena on May 28.
UEFA have now called an extraordinary meeting of their Executive Committee, to be held at 9am GMT on Friday, where the situation will be assessed and "all necessary" decisions taken.
In a statement on Thursday, UEFA said: "Following the evolution of the situation between Russia and Ukraine in the last 24 hours, the UEFA President has decided to call an extraordinary meeting of the Executive Committee for Friday 25 February at 10:00 CET, in order to evaluate the situation and take all necessary decisions.
"Further communication will be made after the meeting of the UEFA Executive Committee."
One member of the Executive Committee is Alexander Dyukov, the president of the Russian FA and chairman of the management board of Gazprom Neft, a subsidiary of UEFA's major sponsor, Gazprom.
UEFA are expected to strip St. Petersburg of the right to host the final, but will not need to name a new venue until the two finalists have become clear - as was the case last season when the final was moved to Porto due to the coronavirus pandemic.
Sadiq Khan, the mayor of London, has said the capital will be ready to host the final if called upon, though Wembley Stadium is already hosting EFL play-offs on the date of the Champions League Final and the Tottenham Hotspur Stadium is currently scheduled to hold rugby league's Betfred Challenge Cup Final.
The operator's of West Ham's ground, the London Stadium, have expressed their interest in hosting the final.
London Stadium chief executive Graham Gilmore told The Daily Telegraph: "We have a great history of putting on world-class events from Major League Baseball to sold-out concerts and of course Premier League matches.
"We are always happy to hear from event holders, and there is a clear track record of the stadium and London hosting the biggest events brilliantly."
