Brazilian twins Rafael and Fabio have already proved themselves more than capable at full-back. Danny Welbeck has just won his second England cap after scoring five times for United - a figure only exceeded by Wayne Rooney.
And Tom Cleverley has just been handed a four-year contract extension as deserved reward for his impressive early-season performances.
Little wonder Evra is feeling vulnerable.
"I'm only 30 but I feel like the oldest player in the team," he said. "I just have to show the young players that I'm still here and I want to play every game.
"I need to prove I am still fit because they are young. Maybe they have more energy and think they can steal my place.
"Of course, though, you also have to help them and talk to them if anything is wrong. We are here to protect them and to show them that it's easy to reach the top, but to stay there is the most difficult thing.
"But before we can say anything to the young players, we have to show our own example on the pitch because the competition is really fierce.
"The boss is not afraid to put the young lads in and it's working well."
