Evra believes Cavani will be the sort of signing that can inject more impetus and character into their attacking play - pointing to the near-instant impact the debutant made.
He said: "Of course it's about the result but that's their way to play, it's their philosophy and DNA.
"This team needs men, they need character.
"You can see when he came on, first touch, he was sharp.
"I know some people would have preferred Jadon Sancho but Cavani is what I'm talking about. People come with no fear."
