Blackburn 0 Man Utd 1:Louis Saha's second-half strike set up Manchester United for a vital victory to keep them ahead of Chelsea in the title race.
The French forward struck in the 64th minute at Ewood Park to secure United's sixth successive Premiership victory.
Ewood Park has proved an unhappy venue in the recent past — this was United's first win in the league at Blackburn's ground since 1998, and it was also their sixth successive victory in the Premiership.
Saha sent a left-footed effort curling wide from 25 yards, then Van der Sar rescued United by punching away Bentley's cross a moment before Benni McCarthy arrived.
With three minutes left, Blackburn were given a free-kick after Van der Sar handled outside his area.
Via Pedersen and Tugay, the ball dropped to McCarthy who rifled a shot towards goal only for the United keeper to save at the second attempt and secure a valuable victory.
