The Manchester United manager surprised many when he left Rooney out of the starting line-up to face Inter Milan in the UEFA Champions League.
The 23-year-old came on as a late substitute in the goalless draw in Italy, seeing only seven minutes of action and receiving a booking.
Ferguson has revealed that there are likely to be many changes in the side for the showdown with Tottenham at Wembley.
"I just have to wait and see what the manager says about Sunday,"Rooney said.
Squad"All the players want to play, it is a cup final. But it is down to the manager because it is about the squad and how he thinks it should be used."
Rooney says that United had should have come away from Stadio Giuseppe Meazza in command of the tie with Inter.
He recognises the threat posed by Jose Mourinho's side but is confident the Red Devils can progress if they repeat their recent home performances in the second-leg.
"We had enough chances to give ourselves the best chance of going through," he added.
"It is a dangerous scoreline. If they get one goal it is going to be difficult for us.
"I have seen a few of Inter's games and it seems to me like Inter are probably better away from home. They can just sit there and defend, then try to hit you on the break.
"But it is also a good result because our own home form is excellent, so if we defend well and take our chances we will be OK."
