Goalscorer Dimitar Berbatov claimed the result was all that mattered as Manchester United beat Blackburn to stay within two points of Premier League leaders Chelsea.
The Red Devils spurned several chances to make the result more comprehensive at Old Trafford, but the Bulgarian scored the opener before Wayne Rooney made the game safe.
Berbatov was not concerned by the scoreline, and told ESPN: "One-nil is good as well as long as you get the three points. Two-nil, four-nil, it doesn't matter - as long as we keep on winning I think everyone will be happy. In the first half, I had a couple of chances to score - you need to be patient and when another chance comes, you need to score it.
"I was glad that I scored my chance, and Wayne Rooney scored another one and it was finished for Blackburn. It is always difficult to play against Blackburn, but always when you score a goal you are relieved because you feel that you have done something special, and that was the case.''
Manchester United manager Sir Alex Ferguson offered some sympathy to Gabriel Obertan after the Frenchman squandered two gilt-edged chances.
''Gabriel was a bit nervous when he came on,'' he said. ''It was only his second game in seven months, so you have to put it in perspective. But then he settled down and did well. He is not happy with himself and that is a good thing.''
However he confirmed that Rio Ferdinand and Ryan Giggs would miss the Champions League match against CSKA Moscow through injury.
Ferguson said: ''The players worked very hard as Blackburn set out their stall. You always get a bit concerned when you haven't scored. But we don't panic. We have that experience. We can win games in the 93rd minute. You need that patience, though, and we improved our penetration in the second half. That is a strong virtue of this club.''
