It takes Alan Pardew's squad to ten French speakers, including Cheick Tiote, Gael Bigirimana and Papiss Cisse.
Lyon's Belgian midfielder Steed Malbranque: "It will be a problem, I think, because without meaning to, at the beginning, the French players will stick with each other.
"If some of them don't speak any English then they will only talk to the other Frenchmen.
"That could lead to the creation of cliques and could create problems in the squad. I hope not for them but there is a risk.
"At Fulham, we didn't have any major problems, but it is true that we French often kept to ourselves.
"There was a little bit of tension, but once the French coach left things were different.
"The coach must fix the rules. Tigana made us speak English to the other French players to show the English guys that we were making the effort.
"There were little things like that. I don't know Alan Pardew, but if there are no rules then there will be problems.
"They are going to be cold! It will be tough! The atmosphere in Newcastle is good but they will still feel the cold."
