Elsewhere, Queens Park Rangers gave Harry Redknapp the perfect 66th birthday present with a 2-1 win at Southampton and Everton kept their pursuit of a top-four finish on track with a 3-1 victory over Reading.
Here is the best of the Twitter reaction, in chronological order, to a hectic afternoon of Premier League action.
United defender Rio Ferdinand (@rioferdy5) lavishes praise on his Japanese team-mate: “#KagawaHattrick lovely! First Asian player to score a hat-trick in the EPL……”
It sparks debate with former Red Devils goalkeeper Peter Schmeichel (@Pschmeichel1): “RT ‘@rioferdy5: #KagawaHattrick 1st Asian player to score a hat-trick in the EPL……’ No Asian player has ever scored two goals in a game..!! Ok guys I surrender. Park scored two versus Wolves December 2010…!! I watched the match today on DK TV, and the stat came from there.”
Former Liverpool midfielder Didi Hamann (@DietmarHamann) reckons QPR have stolen the headlines on Saturday: “Result of the day has got to be QPR’s win at Southampton, gives them a fighting chance. The bonding trip must have worked. Well done Harry.”
