France is bracing for Eric Cantona's bank-run revolution Tuesday, with the government criticising his call for the public to stage a mass cash-withdrawal and the left questioning whether it would have much effect.

When the former Manchester United footballer gave a video interview in October calling on citizens to stage a cash-point revolution, protest groups against the financial system decided to coordinate a world-wide withdrawal on December 7, the number of Cantona's lucky shirt.

Asked about street demonstrations to protest against government austerity measures, Cantona said: "We have to change the way we do things nowadays. Talking of revolution, I don't mean we are going to pick up guns and go out to kill people. Revolution is very simple to do nowadays," he told the French paper Presse Ocean.

"What's the system? The system revolves around banks. The system is built on the banks' power. So it can be destroyed by the banks. Instead of having three million people going out to demonstrate with a placard, those three million people go to their bank branch, they withdraw their money and the banks crumble." He directed people: "You go to your bank in your village and you withdraw your money." But as tens of thousands of people signed up to the online campaigns led by a Franco-Belgian anti-bank protest group, the French government warned against "Eric Le Rouge" sticking his nose into economics.

Francois Baroin, the budget minister, said: "It would be funny if it wasn't so tragic." FCantona's call to arms was "grotesque" and "not serious". inance minister Christine Lagarde said witheringly: "There are those who play football magnificently, I wouldn't dare to try. I think it's best for everyone to stick to their own speciality." The director general of BNP Paribas deemed Cantona's appeal "ill-founded".

Cantona told the daily Liberation that he would heed his own call to withdraw money. "Given the strange solidarity that has sprung up, yes. On December 7, I'll be at the bank." Online supporters have pledged that they will either definitely or probably withdraw cash. They are aiming for a bank-run like that which hit the UK's Northern Rock in 2008.

But even the left has queried the idea, saying supporters don't have enough clout to dent the banks.

Olivier Besancenot, the French postman who head of the New Anti-capitalist party, said "I like this desire for revolution. But in reality, the people who would dream of taking part in this don't really have enough money in their accounts."

In Le Monde, the commentator Pierre-Antoine Delhommais quipped that he hoped Cantona would hire a lorry o withdraw his own "sacks of cash", as "one imagines he hasn't worked for free for all these years, advertising the merits of Bic razors, Nike shoes, Partouche casinos, Neuf Telecom, Lipton Teas, the Renault Laguna or L'Oréal deodorants."
