Amid claims of splits in the Magpies camp, which have been strenuously denied by manager Alan Pardew, Ginola has admitted some of his compatriots may not realise the importance of the club remaining in the Premier League.
Newcastle signed Mathieu Debuchy, Massadio Haidara, Mapou Yanga-Mbiwa, Moussa Sissoko and Yoan Gouffran during the January transfer window in a bid to drag themselves up the league table.
Ginola told talkSPORT: "I spoke a few weeks ago about the fact there are 10 French players in the squad and whether it would be a good thing for the club.
"At the time, it seemed that it was positive because they were going to bring something different to the club, but after a few weeks, it wasn't good enough and it still isn't now.
"Playing in Europe and then in a Premier League relegation fight are completely different things.
"You have to have the right sort of players for that task and I'm not sure that the players are concerned about it.
"The players are thinking, 'Well, if the club is relegated, then we will leave in the summer'.
"Hopefully they are going to find something to help save the club because Newcastle United and the fans need to stay in the Premier League. I hope they are impressing that importance onto them."
