Man Utd keeper Van der Sar: Derby win incredible feeling
Paul Scholes' 149th goal for United from midfield moved him into 10th place in the all-time United goalscoring list - one behind Dutch striker Ruud van Nistelrooy.
Van der Sar said: "It's an incredible feeling for the players and the fans.
"But you kind of get used to it, because it's the third time this season we've done it against City.
"Last week against Blackburn was disappointing. Normally, when we keep a clean sheet we get a goal.
"Yet we were a bit flat last weekend.
"The only thing we could do was win this and hope Tottenham would do something for us.
"All we can do is win our games and try to delay things as long as possible - and that's what we did."
