Chelsea fans have expressed concern after Roman Abramovich confirmed he is looking to sell the club, while those who have travelled to Luton have been heard singing his name.
The decision came after it was reported the oligarch could be stripped of assets as part of Britain's sanctions against Russia following the invasion of Ukraine.
That would have potentially meant Chelsea being taken out of his control, leading to the "difficult" decision to officially put the club on the market.
A number of businessmen have already been rumoured with a consortium bid, including Hansjorg Wyss and Todd Boehly, who previously attempted to buy the Blues in 2019.
In his statement, published on the club's official website, Abramovich confirmed the decision but insisted that a decision would not be fast-tracked and that a charitable foundation will be set up to aid those suffering as a result of the conflict.

But many Chelsea fans were left concerned by the news.
@Legend_Azpi said: "I hope he sells it someone who will care for the club like he did."
@Mattisearmani said: "Im finished."
@Greener_16 said: "Not really sure what to make of this."
@Komrade_Konrade said: "So sad he had to do this. This is terrible."
@FrankKureoma said: "A very difficult and heartbreaking decision. I can't believe a day like this will come one day during the Roman Abramovich era. Chelsea FC without this Man is not the same."
Fans who had travelled to Luton for their fifth-round FA Cup clash were also heard singing the name of the Russian ahead of kick-off in a show of support for their long-term owner.
Abramovich continues to be held in incredibly high regard by many supporters with the club having risen to become one of the best in the world under his ownership.
But he came under fire last week for repeatedly failing to condemn Russia's involvement in the latest conflict, something he did not do in his latest statement either.
