The performance caps what has been an outstanding start to the season for the Bulgarian, in which he has been United's most prolific attacking player, ahead of an out-of-sorts Wayne Rooney.
This comes after two seasons at the club in which the former Tottenham and Bayer Leverkusen man has failed to live up to his price tag, which was an initial £23.4 million, plus the loaning out of Fraizer Campbell and further bonus payments which made the fee reportedly go above the £30m mark.
He failed to find the net with as much regularity as he had at Tottenham and also could not find his ideal within the United team.
Team selections suggested he lost the faith of Sir Alex Ferguson, after being continuously left out of starting line-ups for big games, though publicly, the Scot remained in full support of his star signing.
This summer, the support for Berbatov from Ferguson was stronger than ever, and he has now scored an astonishing seven goals in six appearances so far this season, including a stunning overhead kick as the second in today's hat-trick.
Having been written off as a flop after two underwhelming seasons at Old Trafford, how far along the road to redemption is Berbatov? Has he proven he's back to his best and can play a vital role in the team? Will he never be worth his price and place in this squad or is there yet more to be discovered about the mercurial Manchester United No.9?
