But Scholes believes Cavani will not take Ole Gunnar Solskjaer's side to the next level.
Scholes, who has suggested United should have targeted Borussia Dortmund's Erling Haaland instead of his team-mate Jadon Sancho in the summer transfer window, doesn't think Martial is capable of leading the line for his old club in the long-term, despite his impressive individual ability.
Cavani has only signed a one-year deal with Manchester United so Solskjaer could have a void to fill at the end of the 2020-21 Premier League season.
The 33-year-old was a free agent after he was released by Paris Saint-Germain earlier this summer and the Uruguayan striker hasn't played competitive football since March.

However, minutes after the cease-fire took force, both sides accused each other of continuing attacks in violation of the deal. Mnatsakanyan was due to meet the Minsk Group co-chairs in Moscow after his discussions with Lavrov.
The absence of the classy front pair will force Solskjaer to look elsewhere for a centre-forward against Newcastle as the Reds look to bounce back with three points'.
Asked what sort of season he expects Cavani to have, Scholes told Stadium Astro: "Well, we'll have to wait and see won't we".
"There's been a lot of money spent but has it been spent on the first choices these managers want?"
"I think Ole's been supported. It's misleading. That's why I've kept saying we need a top-class No. 9".
Apparently, Manchester United were holding out for £8 million for the keeper. Cavani, he should be a loan signing.
