The Eintracht Frankfurt striker is the latest to be linked to the Old Trafford club this summer.
With The Athletic outlining that United are negotiating with Frankfurt to secure Kolo Muani, Saha weighed in on the young Frenchman's qualities.
"Randal Kolo Muani has different type of qualities to Harry Kane and he's still young," Saha told Betway.
"But Muani has a hunger to always score goals, keeps himself busy on the pitch and can be very versatile. It's a player who the Manchester United players will find easy to play with because he's very smart in the way he plays.
“Muani won't have any issues with the fitness or physicality needed in the Premier League, he can run all day and press high-up like we've seen with Wout Weghorst. He's shown it for France with Kylian Mbappe, they connected instantly."
