Patrice Evra says Edinson Cavani's sharpness and character convinced him that the striker will be a good signing for Manchester United.
The new signing came on for his debut as a substitute in United's dull goalless draw with Chelsea and almost scored with his first touch as he diverted a cross narrowly wide.
It was one of the few chances in a game more notable for how defensive both teams were as they cancelled each other out.
Speaking post-match on Sky Sports, Evra was unimpressed with the way both teams set-up as they focused on getting a clean sheet instead of scoring.
Fellow pundit Jimmy Floyd Hasselbaink accused the former United full-back of being hypocritical due to the fact he used to play a similar way for Juventus. Yet Evra argued that style is part of Juve's philosophy but not the way United and Chelsea traditionally operate.
Instead, he 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.
"For Chelsea and United, it's not in their DNA to play that way.
"We need fear, we need men, we need character, that's why, people may not agree with Edinson Cavani, but for me he's a great signing.
"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."
