Telecommunications firm Three have confirmed that they are placing their £40m a year shirt sponsorship deal with Chelsea "under review" in the wake of the sanctions imposed on Blues owner Roman Abramovich.
The billionaire has had his assets frozen in the wake of Russia's ongoing invasion of Ukraine, although he continues to deny any links to president Vladimir Putin.
Chelsea have been given a sporting licence to continue playing and trading despite the move, although the measures will put a block on Abramovich's proposed sale of the club.
