The sanctions against Chelsea owner Roman Abramovich appear to have cost the club the chance to sign Gabriel Slonina.
The UK government has frozen Abramovich's assets in the country due to his previous ties with Russian leader Vladimir Putin amid the war in Ukraine. The club are now operating under a special license that does prevents them negotiating new contracts with their players.
Chelsea are also unable to bring in new players though, meaning they will have to put any possible deals they were hoping to complete on hold. Transfer expert Fabrizio Romano claims the Blues were in advanced talks to bring in Chicago Fire goalkeeper Slonina.
