United came back from 2-1 down to defeat Stoke City 3-2 on Saturday.
Evra said: "We can't win one game and draw the next one, or lose it.
"We want to win two or three games in a row but it is when we win 10 games in a row, that I will say Manchester United are back in business.
"At the moment we are not.
"We have to make sure, even if we do it in a bad way or an ugly way, we win games.
"We need to win those 10 games. We don't have any choice. After that we can play the beautiful football."
