French president Francois Hollande has pledged to stick to a plan to impose a super-tax on football players' salaries despite the threat of the nation's professional clubs to scrap games one weekend next month.
Mr Hollande told reporters at the European Union summit that "the law must be the same for all" once the plan to implement a so-called 75% tax law on income above a million euros per year is approved.
The law would mainly affect the clubs rather than the players as it is geared toward making employers bear the tax burden.
Jean-Pierre Louvel, president of the Union of Professional Football Clubs, says the law would be "the death of French football" if it is pushed through. His union has threatened to boycott the round of league games scheduled for November 29 through to December 2.
Mr Hollande said he was willing to meet the clubs next week to address their difficulties but said he would not budge on their main complaint.
Once the plan is voted into law, Mr Hollande said, "it will be the same for all companies, whatever they may be".
The last time games were boycotted in the French league was in 1972, but that was at the initiative of the players.
The tax was a campaign promise from Mr Hollande, who pledged to rein in what he said was excessive executive pay out of line with the struggling economy.
The tax is only supposed to be in place for two years, starting retroactively this year, and the government expects it to net 420 million euros. It would cost clubs 44 million euros over that period.
"Each must know the rule, and the rule is the same for all," Mr Hollande said.
The proposal for such a tax hike was the most memorable promise of his campaign, and polls have shown it was widely popular, even if it generated heavy criticism from business leaders and sports organisations.
Mr Hollande's initial proposal called for individuals - in the case of football, the players - to pay a 75% tax on all income over a million euros. That tax was rejected by a court this year and the budget before parliament would instead put in place a 50% tax, paid by the employer.
