World football governing body FIFA on Monday said it will open a special transfer window to allow foreign players and coaches leave Russia amid the country's invasion of Ukraine.

"In order to facilitate the departure of foreign players and coaches from Russia, in the event that clubs affiliated to the Football Union of Russia (FUR) do not reach a mutual agreement with their respective foreign players and coaches before or on March 10, 2022 ... the foreign players and coaches will have the right to unilaterally suspend their employment contracts with the FUR-affiliated clubs in question until the end of the season in Russia (June 30, 2022)," FIFA said in a statement.

"The suspension of a contract ... will mean that players and coaches will be considered 'out of contract' until June 30, 2022, and will therefore be at liberty to sign a contract with another club without facing consequences of any kind," the statement added.

The players' union FIFPRO, however, said FIFA's move is only a temporary measure that will not provide much help and demanded that players should be allowed to terminate their contracts.

"The decision ... to allow foreign players to only suspend their contracts and thus only temporarily leave Russian clubs is too timid," FIFPRO said in a statement.

"It will be hard for players to find employment for the remainder of the season with uncertainty looming over them and, within a few weeks, they will be in a very difficult situation once again.

"It is unsatisfactory even for players who are tied to short-term contracts in Russia – where contracts typically end in December – and who may not want or be able to return after 30 June 2022 ... FIFPRO communicated to FIFA last week that these players should be allowed to terminate their contracts."

FIFPRO asked that FIFA, and its European counterpart UEFA, set up a fund to help players and coaches in Ukraine.

"It is disappointing that other stakeholders in this process were not prepared to agree to this important step," it said.

"For players, coaches and others in Ukraine, we consider it essential that UEFA and FIFA widen professional football’s response to the war by establishing a fund to support all those in the industry who are affected."

Russia calls its actions in Ukraine a "special operation" designed not to occupy territory but to destroy its neighbour's military capabilities and capture what it regards as dangerous nationalists.
