Manchester United manager Sir Alex Ferguson is expecting a tight game against Chelsea at Stamford Bridge on Sunday.
The Red Devils came out 3-1 winners at Old Trafford earlier in the season.
"That was a crazy game," Ferguson told reporters. "It could have been 20-18. I don't think it will be like that on Sunday. It will be much tighter.
"It's not going to be an easy game. In the last seven years there have been many terrific battles with Chelsea."
United are currently second in the Premier League table on goal difference behind local rivals Manchester City.
