France had a Mundial to forget in 2010, crashing out in the group stages amid in-fighting and unrest within the squad.
Yet Evra insists his side are a changed team from 2010, where the focus is now more on the team than individuals.
“You need everyone in the World Cup, you cannot give up because you’re not starting a game,” said the Manchester United defender.
“We do not have a problem with egos in this team.
The 33-year-old has also heaped praise on manager Didier Deschamps who is able to motivate the team and get the best out of his players, despite his merciless approach.
“Nothing’s ever certain with Deschamps,” Evra said. “That’s why I like to work with him. He never gives you presents.
“He’ll look you in the eyes and say, ‘Pat, if you mess up I won’t spare you’. I know that if I step out of line I’m out of this team.”
Evra feels the team cohesion in the French squad is a major asset for his side in this year’s tournament.
“I have faith in this squad, and that’s a great strength,” he said.
“The star isn’t one player, it’s the team.”
France next face European rivals Switzerland in their Group E encounter in Salvador on Friday.
