Roman Abramovich has been added to the government's sanctions list, with all of the 55-year-old's UK assets - including Chelsea Football Club - frozen with immediate effect.
Chelsea will be allowed to continue functioning with restrictions under a special sporting licence that expires at the end of May but the club's sale has been placed into doubt and the owner will no longer be permitted to invest in the club.
There is also a lack of certainty over what this means for the Blues' transfer dealings going forward. While the sanctions state that only “inter-club payments to discharge obligations which existed before 10 March 2022 under player loan/sale arrangements” will be permitted, the license Chelsea have been given to continue operating only lasts until May, meaning things could be different by the time the summer window opens in July.
