Corentin Tolisso slammed fans for whistling at Paul Pogba during France's friendly win over Italy.
Goals from Samuel Umtiti, Antoine Griezmann and Ousmane Dembele earned Didier Deschamps' men a 3-1 victory in Nice on Friday.
"We're France, whether we go to Nice, Lyon or Saint-Etienne. Everyone represents the French team," he said.
"The fans came to support the French team. Personally, when you witness this kind of whistling – and I also noticed some for Florian Thauvin – it's exasperating, it annoys me.
"We're France, we are all France players, we're all fighting for our country and for the fans there and we produced a very good performance.
"Paul had a good game, he worked hard. It hurts because I wouldn't want to be whistled, even if I went to Saint-Etienne as an ex-Lyon player.
"Fans need to realise this. We're all on the same boat, and we have to all stick together."
France will go into the World Cup as one of the favourites, facing Australia, Peru and Denmark in Group C.
