Man Utd boss Ferguson: Vidic outstanding for Everton
It was Vidic's first full match in the Premier League this season.
Ferguson told MUTV: "That was a fantastic performance by him [Vidic]. Every ball that came in he got it clear, and that's his specialty: he's a fantastic header of the ball. That was the key to us today.
"All the midfield players were terrific too, in the first half, and Danny Welbeck and Ji-sung Park had some great interchange play.
"The goal was an absolutely brilliant goal and Chicharito does what he does best and got us the goal that won the match."
