The Sevilla players wore the logo, a dig at France's national motto, though the Spaniards substituted 'superiority' for 'fraternity' on their shirts during their league match with Real Sociedad - who refrained from such a gesture - in the latest offering in the bitter war of words between France and Spain.
The Spanish have been up in arms since French satirical puppet show Les Guignols implied tennis great Rafael Nadal and other athletes are drug cheats following the two year ban imposed on two-time Tour de France champion Alberto Contador for doping last week.
In a recent video parody of Spanish athletes, a puppet of disgraced cyclist Alberto Contador sings that he's got bull's blood in his veins.

In another, a satirical advertisement asks people to donate blood to Contador and thus share in the glory of his cycling victories.
One sketch featured a puppet likeness of world number two Nadal refuelling the tank of his car from his own bladder, which powers the car and leads to him being pulled over by police.
Another depicts Nadal boasting about a stash of clean blood hidden in his fridge.
“This isn't an attack against me,” Nadal told reporters, “but an attack against Spanish sports and the Spanish people.”
Sevilla management issued a statement explaining why they had allowed their players to take to the pitch with the slogan on their shirts.
"This is to show our support for all sportsmen in the country," the club said.
"We also wanted to take the movement a step further in our resolute defence of the Spanish sporting world."
Les Guignols are a cross between saturday Night Live and the Muppets.
The sketches on French TV prompted the Spanish foreign minister to order a formal protest to French media.
In recent years Spain has dominated the sporting world in soccer, cycling, tennis and basketball.
