The Red Devils go up against Braga in the Champions League this evening and the Scotsman has insisted that his team's set-up could be "revolutionary".
"The game in England and Europe is at such a high level now that making yourself unpredictable is going to be a strength," said Ferguson.
"Opponents will have to think if we are going to play two wide players or the diamond because we have players capable of different things. We have had some success playing with the diamond.
"But the history of the club has always been to play with wide players, particularly at Old Trafford, so I have a decision to make. If it turns out we play the diamond it would be revolutionary because it is going against our history."
The former Premier League champions currently sit at the top of Group H with six points.
