While the livewire Rooney notched his 31st and 32nd goals of a remarkable season, languid Bulgarian Berbatov provided the perfect foil with a display that oozed class.
Berbatov, who has never completely won over the Old Trafford faithful, produced a brilliant piece of play to set up Rooney's second goal and got on the scoresheet himself to take his tally for the season to 10.
While that is hardly prolific for a player of Berbatov's pedigree who has enjoyed being top dog at most of his previous clubs, Ferguson was more concerned with his silky contribution in other areas.
"The work by Berbatov was fantastic football and he just laid it on a plate for Wayne who took it well," Ferguson told MUTV. "He (Berbatov) is intelligent, he has good composure on the ball and he adds to the team all the time.
"The making of the second goal was absolutely superb. It was very important (for him to score later), because he had a few opportunities, but he took one."

Rooney opened the scoring 30 seconds after the interval and struck again with six minutes remaining after Berbatov jinked down the right and pulled back a perfect pass.
"Fulham made us work because they've got good possession of the ball, they have composure and experience on the ball and they made us chase all over the pitch, particularly in the first half," Ferguson said.
"The start to the second half was crucial and we got a good one to put us in a good position."
