The Brazilian has been challenged by Sir Alex Ferguson to double his current tally of three strikes before the season is out. "I have told him if he manages six by the end of the season, I'll give him £50 for a new haircut!" the boss wrote in United Review.
However, it has been quality over quantity for the outstanding full-back, who also won this accolade back in September for his belter at Liverpool.
Rafael's howitzer past fellow countryman Julio Cesar collected a massive 93 per cent of the vote, well clear of second-placed Wayne Rooney's winner at Fulham and Nani's effort against Reading, which came third.
Thanks to everyone who voted on our websites - one of the voters, selected at random, wins a United shirt signed by Rafael. Congratulations to Lukasz Lipinski from Poland.
