Chelsea technical and performance advisor Petr Cech has admitted that the west London club does not know if they will be able to offer contracts to players whose deals are set to expire at the end of this season.
Chelsea owner Roman Abramovich was placed under a series of strict sanctions by the UK government on Thursday as they continue to crack down on wealthy Russians with assets within the UK. The move came just two weeks after Russia invaded neighbouring Ukraine.
It means that Abramovich's assets have been frozen under the move and he faces tough measures on transactions in the UK with both individuals and businesses. Therefore, Chelsea are currently banned from selling tickets and merchandise, signing new players, selling players, offering new contracts to players and staff and are limited to spending just £20,000 on travelling to and from fixtures.
