Ferguson has not lost sight of the fact his star forward has already contributed 12 goals to the United cause this season, and 158 overall in a United career now into its eighth year.
It is not a tally he can afford to abandon.
"Strongly is not the appropriate word," said Ferguson, when asked about the level of thought he was giving to turning Rooney into a permanent member of his midfield until.
"It is conditional on the midfield players I have available.
"Tom Cleverley is injured. Michael Carrick just started training and wasn't available on Wednesday. I was limited in my choice.
"There was a thought we might play Phil Jones there but we decided on Wayne.
"He has the appetite for it. He has the energy levels and I thought he did that really well.
"But I am not putting any marker down for that position.
"When you have a player who has scored 12 goals so far, you want him to be in positions where he can get you more goals. That is where he normally plays."
