Ferguson is ready to break up his dream team pairing of Robin van Persie and Wayne Rooney over Christmas, despite their goals firing Manchester United to top spot and heading towards a Premier League scoring record.
Ferguson, who has avoided rotating his £50million strikers so far, feels he has to change his policy to cope with a run of four games in 10 days, starting against Swansea City on Sunday afternoon.
"December has already been a hectic month and now we have this run of four games in 10 days - and then the FA Cup begins. That's quite a programme," said Ferguson. "Using our pool of players will be important for us.
"It will be a different team every game, absolutely no doubt about that. All the players will be involved, I will definitely be making changes."
