Bordeaux president Jean-Louis Triaud has lent his support to Ligue 1 presidents who are threatening to boycott playing Monaco next season.
Monaco, managed by Claudio Ranieri, are on the verge of clinching promotion back to the top flight after a two-year absence, but the principality club's imminent return has led to an escalating row and caused Ligue 1 clubs to question their privileged financial status.
A 19th-century agreement between France and Monaco means foreign players at the club pay no income tax, enabling Monaco to pay higher wages than their rivals.
And a deal drawn up between the two in the 1960s means both foreign and French players cost the 2003-04 Champions League runners-up significantly less to employ than they would have cost their Ligue 1 counterparts.
The French Football League's (LFP) Administrative Council recently voted to require all clubs participating in their competitions to be based in France for tax purposes by the end of the 2013-14 season.
However, talks with Monaco over a potential compromise have since been broken off and the club have threatened to go to the courts - and now some Ligue 1 presidents are planning their own offensive.
"It's an extreme line to take. If they're talking about it, it's not by chance. But why not?" Triaud told RMC Radio.
"They'll be top of the table with 114 points. As they'll win all of their games 3-0 by forfeit, they'll have scored 114 goals, have 114 points and conceded none. So they'll be record champions."
