Chelsea should be stripped of every trophy they won with Roman Abramovich's cash, according to football pundit Stan Collymore.
The former England striker said the UK Government's decision to freeze the oligarch's assets over his links to Russian warmonger Vladimir Putin called into question all the club's achievements during Abramovich's two-decade ownership.
If Chelsea's success was built on access to "dodgy" money how could the 21 trophies won with Roman's roubles be allowed to stand, he asked.
Collymore, 51, who played for a string of top clubs including Liverpool, Leicester and Aston Villa before becoming a TV and radio pundit, said punishment should be retrospective as it would be for offences such as doping and match-fixing.
He said though Abramovich, 55, legally took control of the club he had been sanctioned for his historic support of Putin therefore it was logical to consider retro penalties.
It was "the only way for English football to restore sanity", Collymore added.
He tweeted: "So the question now needs to be asked if Chelsea's loans, access to 'dodgy' money and sanctions against its primary source of funds for 20 years is now rubber-stamped how can titles won in this period stand?
"The British Government only knew Abramovich was a Putin accolyte today? Not the other 20 years? Who's leading the security services? Inspector Clouseau?
"When RA bought the club the love of a team had strings attached. An oligarch. You can't detach team from oligarch because team success came directly from him.
"Medals are stripped for doping, so will trophies?
"If someone doped in an Olympics 30 yrs ago they'd still be stripped of the medal now.
"Therefore retro punishment is a logical question to ask. Juventus had titles stripped for match-fixing. Juventus.''
Collymore said if the FA did not look seriously at club ownership they were dead as guardians of the game and fans "would be dragged into geopolitics for generations making our sport nothing more than a pawn".
He said Chelsea fans had bought into Roman too - and chanted his name at Thursday's night's Premier League match against Norwich hours after sanctions were imposed.
"I've yet to see or hear any fan group demand entry to their club to ask questions around the political choices their owners take around the world," Collymore went on.
"That's why sport washing works - they give you nice things to play with and soon you find yourself clapping like a seal."
Collymore's comments sparked a heated online debate.
The Irish Emergency Logistics Team tweeted: "Chelsea FC should be confiscated, sold and all funds raised going to the Ukraine humanitarian response. All titles won during Abramovich time should be struck off the history books."
One fan replied: "I've said this for a long time, all bought and won with 'dodgy cash'."
Another added: "Everyone saying 'can't go back and change the past'. Rubbish. Look at cycling - it stripped Lance Armstrong for cheating. Athletics do it all the time to doping cheats. Juventus were stripped of Serie A for cheating. Marseille likewise. So why not Chelsea?"
But another said: "I enjoy seeing Chelsea in the mud as much as anyone but this is just daft."
One more messaged: "I don't think it's fair to retrospectively decide RA should never have been allowed to buy Chelsea in the first place. If this was nipped in the bud and he wasn't allowed in, maybe that would have been fair game, but he was enabled by the authorities.."
Another wrote: "What are you even saying, Stan? How can titles be stripped when it's the players collective meritocracy that got us there? Money was only used to bring them into the club. Doping contradicts the theory of meritocracy, it implies using unfair means to boost individual performance."
While one more told the pundit: "You make great points but it punishes the fans, the essence of the club. And who do you give them to instead? I think we need to do better going forward, better scrutiny, rather than clubs desperate to get in bed with the first billionaire who shows them a full wallet."
"Careful where you go with this," added another. "Plenty of other clubs have had dodgy money from all sorts of people, right back to the beginnings of the organised game."
No10 urged Chelsea fans not to back Abramovich, adding though it understood their "passion for their club" it was "important to remember that these sanctions are being imposed on those who have provided support to the Putin regime and the brutal assault on Ukraine".
Freezing Abramovich's assets prevents Chelsea from flogging match tickets or mechanise and entering the transfer market.
Government documents accused the oligarch of having a "close relationship" with Putin and suggested steel from his company may have been used in military equipment involved in "destabilising" Ukraine.
