The Russian put the European champions up for sale after the threat of sanctions was raised in Parliament.

The freezing of Abramovich’s assets, which include Chelsea, means the club cannot sell further match tickets.

The move is intended to stop Abramovich making money from Chelsea.

The government has issued a special licence that will allow fixtures to be fulfilled, staff to be paid and existing ticket-holders to attend matches.

Chelsea have said they “intend to engage in discussions” with the government and will seek amendments to the special licence to “allow the club to operate as normal as possible”.

Meanwhile, Chelsea’s shirt sponsor, telecommunications company Three, has requested that the Blues “temporarily suspend” its deal with the club.

Three has asked for “the removal of our brand from shirts and around the stadium until further notice”.

The company added: “We recognise that this decision will impact the many Chelsea fans who follow their team passionately.

“However, we feel that given the circumstances, and the government sanction that is in place, it is the right thing to do.”

Chelsea will be unable to buy or sell players, or offer new contracts, while the sanctions are imposed on Abramovich. Chelsea-owned players who are on loan at other clubs will be able to continue to play for those clubs.

The London club’s merchandise shop has also been shut.

“Once you start digging down into what this could do – yes, they can play their games but will they even be able [to]?” former Chelsea winger Pat Nevin told the BBC World Football podcast.

“Massive amounts of questions but yes, it’s not hyperbole to say the future of the club is in serious danger.”

The government is open to considering a further addition to the special licence which will allow the sale of the club.

A condition for that to happen would be that Abramovich – one of Russia’s richest people who is believed to be close to Russian President Vladimir Putin – receives no funds.

He has previously said that proceeds of any sale would be donated to victims of war.

On Wednesday, there were 20 credible parties looking at a potential Chelsea takeover and interest in buying the club has not been dented, despite Abramovich being sanctioned.

However, the American investment firm – Raine Group – handling the sale has temporarily halted their efforts after the shock of the news and the confusion caused by what happens next.

Culture Secretary Nadine Dorries has said the government is “committed to protecting” the club.

“Football clubs are cultural assets and the bedrock of our communities,” she tweeted.

“I know this brings some uncertainty, but the government will work with the league and clubs to keep football being played while ensuring sanctions hit those intended.”

Dorries later told BBC Sport: “Abramovich has links to Putin, who is mounting a barbaric and evil attack against the people of Ukraine.

“We in this department stand with the people of Ukraine and I’m afraid sanctions have consequences. Abramovich’s actions have consequences too.”

WHAT DOES THE SPECIAL LICENCE MEAN FOR CHELSEA?

• Chelsea are able to pay the wages of all employees, including players and coaching staff
• They can pay “reasonable” costs of travel to and from fixtures but not exceeding £20,000 per game per team
• They can pay “reasonable” costs towards hosting home fixtures, not exceeding £500,000 per fixture per team
• Fans who bought season tickets or individual match tickets before 10 March 2022 can attend games
• Rights-holding broadcasters can broadcast any fixture involving the club

The sanctions were imposed on a day that both Chelsea’s men’s and women’s teams were in action, with the Blues winning at Norwich in the Premier League, and also at West Ham in the WSL.

During Chelsea’s 3-1 win at Carrow Road travelling fans chanted Abramovich’s name.

The Premier League said that it will “work with the club and the government to ensure the season will proceed as planned and in line with the government’s intention”.

The Chelsea Supporters’ Trust has called for the government “to minimise the uncertainty” and to include fans “in any conversation regarding ongoing impacts”.

As a result of the sanctions, the Digital, Culture, Media and Sport (DCMS) select committee will hear from Sports Minister Nigel Huddleston, Football Association chief executive Mark Bullingham and the Premier League’s chief policy and corporate affairs officer Helen MacNamara on Tuesday.

Committee chair Julian Knight said the hearing would “explore issues around the role of Russian money in our national game and will examine the government’s approach to financial sanctions targeted at specific individuals and its general policy on sporting sanctions and boycotts”.

Knight added: “This morning’s announcement that Roman Abramovich has been sanctioned by the government and emerging details of the likely effect on one of the country’s biggest football clubs illustrates the deep and wide-ranging impact such measures will have on sport in this country.”

Since his purchase of the club in 2003, Chelsea have been transformed, setting the template for how much finance was needed to compete at the top end of English football.

In total, Abramovich has loaned the club more than £1.5bn, which has helped to bring great success.

Under Abramovich’s ownership, the club have won every major trophy possible – including the Champions League twice, both the Premier League and FA Cup five times, the Europa League twice and the League Cup three times.

In February, they won their first Club World Cup.

They have also won the Women’s Super League title four times, the Women’s FA Cup on three occasions and picked up the Women’s League Cup twice in the past eight years.

Financial journalist Kieran Maguire told the BBC: “In the short term, it’s to a large extent business as usual. Chelsea will be able to pay wages due at the end of March and will have other overheads.

“Chelsea’s wage bill is round about £28m a month. We don’t know how much cash they have in the bank. The most recent accounts we have are from June 2021 when there was £16m in the bank. Abramovich has been injecting money into Chelsea on a regular basis over recent years and presumably that won’t be able to continue.

“The concern might be what happens if Chelsea’s cash reserves are insufficient to pay their wage bill – but presumably the government and Premier League, who have been working on this, will have been looking at it to try to minimise disruption on a club level.”
