Barca, who also won their title this season, are the pre-game favourites for victory at Wembley on Saturday.
"There is no advantage," Ferguson told reporters this morning. "It doesn't matter. We don't decide those things. I know my players will be ready."
Commenting on the threat posed by Argentinian striker Lionel Messi, Ferguson added: "There is always a solution to every good player. Hopefully we can find one on Saturday.
"They have other good players though, and so do we. That is why it is such an appealing game. I am sure Barcelona are aware of that."
Kickoff on Saturday is at 19.45.
