Prince Albert of Monaco is confident that the Ligue 2 outfit will avoid a proposed tax change with regards to foreign players.
The French outfit have had a law in place in 1869 claiming that a foreign player does not need to pay income tax when signing for the outfit, therefore allowing the club to offer an increased salary.
The administrative council of the French league called for Monaco to begin obeying by the same laws as their fellow clubs, which prompted the Ligue 2 leaders to lodge an appeal to the French Football Federation.
"We will fight all the way against this decision," Prince Albert told Le Parisien, according to ESPN.
"The decision is not yet definitive and we are appealing. I think we have a case to argue.
"I hope that everything will be sorted out eventually, but we will take our fight all the way."
French players within the Monaco squad are subject to income tax regulations, but they are thought to pay around 20% less in national insurance contributions.
