Man Utd can be happy with point - Vidic
"We had three or four chances in the second half and maybe we could have done better on a few occasions, but you have to give credit to Brad Friedel.
"We lost an early goal but we still believed we could score and get a result. It's always tough at Blackburn; it mightn't have been the best performance but we got a good result.
"We still have three games to play in the league and the aim is to win all those matches if we want to be champions."
The 26-year-old, who was stretchered off in Rome on 1 April with knee damage, says he felt fine in his first appearance in four games.
"Yeah, I feel okay," Vidic said. "I felt my knee a little bit today but I'm now ready for the next game."
