That is their worse run since January 1990.After losing 2-0 at Stoke on Boxing Day United drew 0-0 against Chelsea on Monday; van Gaal has overseen 11 goalless draws as United boss, six of those coming since 27 October. However, United have kept seven clean sheets and conceded just three goals in their nine Premier League home games in the 2015-16 campaign.And their 30 points from the first half of the season is their poorest return since the 1990-91 season, when they had 22.Swansea arrive still under caretaker Alan Curtis and are unbeaten in three games, drawing two and going 270 minutes without conceding. However, they have scored in two of their last six games and just three in their last nine.But when these teams met at the Liberty Stadium in late August, Swansea extended their unbeaten start to the season to four games with a 2-1 win with Andre Ayew cancelling out Juan Mata’s opener for United before Bafetembi Gomis struck the winner.That was the Welshmen’s third straight win over United; last season they beat them home and away including the 2-1 win at Old Trafford where Gylfi Sigurdsson claimed the winner.For the Chelsea game Van Gaal recalled Wayne Rooney, but they are still missing Marcos Rojo, Anders Lindegaard, Luke Shaw, Jesse Lingard and Antonio Valencia. Swansea test Eder, Federico Fernandez and Wayne Routledge.
