Manchester United remain five points adrift of Barclays Premier League leaders Manchester City after Javier Hernandez's early goal gave them a 1-0 victory over Swansea at the Liberty Stadium.
The Mexico international struck in the 11th minute, sliding home his fifth goal of the season from Ryan Giggs' pass after Angel Rangel had carelessly given away the ball on the edge of his own box.
Victory gave United their first win at Swansea at the ninth attempt on their first league trip to Wales during the Barclays Premier League era.
Meanwhile, Scott Sinclair missed Swansea's best chance when he miscued with an empty goal at his mercy, but, although they had the better of the play in the second half, the Welsh side struggled to create any opportunities of note.
Michel Vorm again starred for the Swans, and did particularly well do keep out a striker from United winger Nanni.
Ultimately, Sir Alex Ferguson's defence was too well-organised, and the resilience of Nemanja Vidic in particular condemened Swansea to their first home defeat of the season.
