Manchester United manager Sir Alex Ferguson was delighted after seeing his side set a new Premier League record with an 11th straight clean sheet in the 5-0 win at West Brom.
The Red Devils surpassed the previous mark set by Chelsea during the 2004-05 season, with Ferguson full of praise for his defenders and, in particular, goalkeeper Edwin van der Sar, who has not conceded a league goal for 1,032 minutes.
He commented: "The defensive record is a fantastic performance and it is down to the experience we have gathered together in the back four.
"Even though we've had to make changes in the last few weeks because of injuries, they have all applied themselves very well.
"Edwin van der Sar, who has achieved everything in the game, is as delighted as when he saved that penalty kick in Moscow during the Champions League final.
"He was over the moon in the dressing room and that tells you his desire. He has still got that ambitious streak and wants to win all the time."
Meanwhile, Ferguson was also pleased with his side's superb form in front of goal at The Hawthorns.
He added: "We saw a ruthless streak that has maybe not been there this season.
"We hoped it was going to come. We expected it to come become of the standard of forwards we have.
"Tonight was the first indication that it was there. For the first ten minutes West Brom did very well and gave us a bit of defending to do and we were quite resolute at that stage of the game.
"But once we got the ball in their half of the field, we always looked dangerous."
