The bigger picture
UEFA, who are yet to decide whether the 2022 Champions League final will continue to be staged in Saint Petersburg on May 28, are also under pressure regarding their association with Russian energy corporation Gazprom.
A letter sent to European football’s governing body from EU politicians reads: "We call on you to stop considering Saint Petersburg and other Russian cities as venues for international football competitions and to choose as a first and very urgent step an alternative venue for the Champions League final on May 28, 2022.
"In addition, we appeal to you to convene a special meeting of the UEFA Executive Committee, to terminate cooperation with Gazprom as UEFA sponsor and to consider sanctions against individual Russian officials who are complicit in the violation of international law."
Competitive football in Ukraine has been suspended following the Russian invasion, with a number of players and coaches currently trapped in the country as commercial air travel is shut down.
