The 29-year-old has been deployed in a midfield role over the past week as United struggled against West Ham United and Burnley.
In fact, the England captain has been dropping progressively deeper and deeper, sparking a nine-game goal drought for the United talisman.
Former West Ham forward Gale wants to see manager Louis van Gaal use his Red Devils skipper in his most influential position up front.
Speaking to Sky Sports News on Friday, Gale said: “I think he will be getting cheesed off playing in midfield because for me it’s a waste. Harry Kane energises Spurs and Rooney does the same for Manchester United.
“He is better than Falcao, he is better than Van Persie. He should be up front but they haven’t got many midfield options at the moment so he’s doing a job. Rooney is not a Paul Scholes he is a player with cutting edge and should be up front.
“I’ve seen Falcao two or three times this season and it’s without doubt his knee injury has lost him a bit of an edge. As for van Persie, he is a yard off the pace and if you had Rooney up front no doubt he would be scoring goals. If you have that cutting edge, you have to be up front.”
Rooney has scored eight goals and has made four assists in 21 Premier League games under the Dutch coach this season.
The Red Devils are currently in third place in the Premier League table after a 3-1 victory over Burnley at Old Trafford mid-week.
United make the trip to League One side Preston North End in the fifth round of the FA Cup on Monday night with a place in the last eight up for grabs.
