Chelsea owner Roman Abramovich has been sanctioned by the UK government as part of a response to Russia’s ongoing military conflict in Ukraine.
He is one of seven further oligarchs to have their assets frozen over alleged links to Russian president Vladimir Putin.
Chelsea have been granted a special licence to continue operating, but their business operations will be significantly limited, with restrictions placed on ticket sales and merchandising, as well as the signing of new players and new contracts.
Earlier this month, Abramovich announced that he was selling the club after more than 18 years of ownership.
During that period the 55-year-old has overseen unprecedented success, with Chelsea winning 19 major trophies, including five Premier League titles and two Champions Leagues.
Clinching the Club World Cup earlier this year meant Chelsea had won every major trophy possible under Abramovich’s ownership.
Prime Minister Boris Johnson said: “There can be no safe havens for those who have supported Putin’s vicious assault on Ukraine.
“Today’s sanctions are the latest step in the UK’s unwavering support for the Ukrainian people.
“We will be ruthless in pursuing those who enable the killing of civilians, destruction of hospitals and illegal occupation of sovereign allies.”
Chelsea are in next action when they travel to Norwich in the Premier League on Thursday.
