Visitors ease through with plenty to spare as Ferguson's reserve side put the ghost of the derby day defeat to rest
Berbatov opened the scoring in the 15th minute following a well-worked passage of play before Owen doubled the lead before half-time. Valencia added the gloss to the result three minutes into the second-half with a wonder-strike from 25 yards as United eased into the next round.
United were the dominant team from the off, keeping possession among their defenders until one of the attackers dropped deep for the ball.
Nemanja Vidic would have been hoping for an altogether quieter night than last week's Champions League game against FC Otelul Galati, in which he was sent off.
However, the United captain was in the thick of it as he picked up a booking in the ninth minute for a foul on Alex Rodman, bringing down the midfielder as he looked set to go through on goal.
But any nerves United may have faced were eased in the 15th minute as Berbatov put the visitors one up.
It was a simple goal from the away side, given too much room by the Aldershot defence following a corner, as Cleverley, Mame Biram Diouf and Park combined well to find the Bulgarian who found the bottom corner.
Owen dealt a hammer blow to Aldershot’s hopes five minutes from the break as the striker picked up the ball on the halfway line before turning and firing a ball out wide to Berbatov.
The Bulgarian toyed with his marker, waiting for Owen to arrive, and he picked out his strike partner easily to fire home.United came out after the interval with a swagger as Valencia found the top corner with a fabulous drive from 25 yards just three minutes into the second half.
That goal took the sting out of the game, and United went about securing the win. Ferguson brought on his latest academy players to impress in the form of Paul Pogba, Ravel Morrison and Michael Keane.
In truth, the match was already over; Berbatov had a late free-kick well stopped by Ross Worner after Park stumbled towards goal, but any real attacking intent was extinguished with Valencia's goal.
United ultimately advanced to the quarter-finals with ease, as their class showed despite Aldershot's best efforts.
