Tony Pulis admitted it felt brilliant after beating Manchester United for the first time.
Pulis watched Albion earn back to back victories at Old Trafford after Jonas Olsson's deflected effort.
The victory moved the Baggies on to the 40-point mark - the figure Pulis set for survival when he arrived at the club four months ago.
"Beating any of the top four or five teams is brilliant and something the players will take on board," he said.
"But it's not the first time we've beaten United, many of the lads were part of the side that did it last year.
"It's now 10 clean sheets since I arrived. But the key to staying up is to get points.
"This is a massive, massive result for us."
