Manchester United boss Sir Alex Ferguson has piled praise on his record-breaking defence.
The Red Devils stretched their formidable run of clean sheets to 11 games on Tuesday with a 5-0 mauling of West Brom.
The Hawthorns demolition saw the Premier League leaders surpass Chelsea's record of 1,025 minutes without conceding a goal set during the 2004/05 campaign.
Ferguson knows title challenges are built on solid foundations and is delighted for his back four and veteran keeper Edwin van Sar, who has taken as much pleasure from his latest achievement as he has from any of the many accolades he has accumulated throughout his distinguished career.
The United manager said: "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 (last season).
"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."
