"He is a good manager, I think he can do a good job [at Manchester United]," the Spaniard told reporters.
"We want to win on Sunday, I don't expect any draws. We have to approach the game to win, and see what happens after that."
The 53-year-old, who led Chelsea to their first ever Europa League trophy on Wednesday, has also targeted a third-place finish for his side.
"It would be a pity after the season we've had not to finish in the top three," continued Benitez. "This is a very good group of players.
"I am sure they will improve and with the experience from this season, really push on next year"
The Spaniard has envisaged a "bright future" for the Blues, hinting that owner Roman Abramovich will give Chelsea's next boss - expected to be Jose Mourinho - a £100m transfer budget this summer.
"What I am sure about is that next season Chelsea will be much better because they will spend £100m and they will sign three or four players," the 53-year-old told Spanish radio station Onda Cero.
"The foundation is already there. The future is bright for them. I don’t know who the next coach will be, I am not the one who should say, even though everyone speculates the same person."
