United beat Blackburn 2-0 on Monday evening to move five points clear at the top of the table ahead of second-placed Manchester City, although they had to wait till the final minutes to secure the win.
Antonio Valencia crashed an effort in from an acute angle before Ashley Young's turn and finish ensure the points soon after.
"They are saying was it a cross or a shot. It doesn't matter," said Ferguson.
"He hit it with such power it was always going to be a problem for the defenders.
"It was a fantastic finish. I thought he was the best player on the pitch."
However, Ferguson does not believe his side can now be considered as favourites for the title.
"We've still got seven games left. In my experience of these situations, it doesn't matter what the points are at the moment," he told Sky Sports 1.
"It matters about next Sunday's game [against QPR]."
"They are all big games now," he said.
"It doesn't matter if it is next Sunday, next Wednesday, the Sunday after that, they are all big ones.
"The players are prepared for that. We will fight right to the end in all the games for the right to win the matches."
The Scot admitted his team were made to work hard by a hard-working Rovers side.
"It was a long night. We had to persevere and persevere. We got our rewards," he said.
"We weren't making any clear-cut chances for a long time.
"But it was an important win and it typifies the history of the club."
Ferguson felt he was also indebted to goalkeeper David de Gea, who made three good saves in the first half to prevent his side from going behind.
"The progress is obvious for all to see," he said.
"He's growing in stature and confidence. He made three great first-half saves.
"David kept us in the game. We had a lot of possession, but we just couldn't get that goal with the way Blackburn defended deep."
Young hailed the overall display from the team in what he called a 'massive' victory for the Red Devils.
"I think this was a massive game for us. We knew if we won we would go five points clear," Young said.
"It was a great result, a great performance."
The win was United's seventh league success on the spin as they have fully cashed in on City's struggles to take over the title race.
United next meet QPR, who moved out of the drop zone at the expense of Blackburn following Monday night's result, at Old Trafford before City meet the Gunners later that day.
"It's crucial time in season. Everyone knows that," said Young, who admitted Valencia's goal came as a relief.
"To get that goal, we knew it would come at some point, whether it was a shot or cross it went in the back of the net."
Valencia capped another impressive performance with a memorable goal, but asked whether it was a cross or shot, he joked: "It was 50-50."
Rovers boss Steve Kean saw his side drop into the bottom three but believes they showed enough to suggest they are capable of avoiding the drop.
"If we can play at that standard for next seven games - not for 80 mins but 90 - we'll get plenty of wins," he said.
"We've got to take all the positives out of the first 80 minutes. We've got to set that standard.
"We were playing against the potential champions.
"I think for 80 minutes we gave it a really good go. Their goalkeeper has had a very good night. He's made good saves when we've had our little opportunities.
"I thought (Junior) Hoilett and Yakubu caused them problems."
