BBC Sport - Swansea v Manchester United Barclays Premier League Venue: Liberty Stadium Date: Sunday, 23 December Swansea goalkeeper Michel Vorm is expected to return after an eight-week absence with a groin injury. Pablo Hernandez is available after recovering from a thigh problem, but Angel Rangel is again likely to miss out with a calf injury. Fit-again Manchester United defender Nemanja Vidic could start his first match since September. Shinji Kagawa is not ready for his comeback, while Rafael remains out with a hamstring injury. So Manchester United are on top of the tree again at Christmas. It might seem as traditional as Santa, tinsel, turkey and Slade on the radio ad nauseam but it's not strictly true. In fact it's only the eighth time United have been the Christmas number one under Sir Alex Ferguson and, surprisingly, on just four of the seven previous occasions did they go on to win the Premier League crown. So if you're tempted to think that a six-point lead over Manchester City is unassailable, think again. Of course Fergie won't be entertaining any such nonsense. He knows that unprecedented 20th title is still some way off yet but he'll be thrilled by his team's fantastic form that's seen them win five on the spin, including that potentially pivotal triumph on City turf a fortnight ago. The goals have been flying in with Wayne Rooney now back in the scoring groove and threatening to challenge Robin van Persie for the Golden Boot. Last time out at home, Swansea were 3-0 down by half-time against Norwich City. Michael Laudrup knows his team cannot be anywhere near as generous with United hunting for more points. Consecutive defeats may have checked the Swans' progress but these are still exciting times in South Wales. They're already five points better off than a year ago and a first ever League Cup semi-final is on the New Year fixture list. That cup run, plus their recent away win at Arsenal, are the major highlights in an impressive campaign - but success over United would surely eclipse both. In Michu they possess a genuine goal threat, and a fit-again Pablo Hernandez would certainly enhance their chances. If they can rediscover the crisp passing, fluid movement and deadly finishing that did for West Brom on my last visit to the Liberty Stadium, Swansea might just pull it off... but I wouldn't put any money on it. What I will predict are goals, a fabulous atmosphere and of course Slade on the tannoy wishing it could be Christmas every day. Manchester United's 1-0 win at Swansea last season was their first victory away to the Welsh side (W1, D2, L6). Swansea City Jan Vertonghen's winner for Tottenham last weekend was the sixth goal Swansea have conceded from indirect free-kicks this season - more than any other top-flight side prior to this weekend. Only seven of Swansea's 26 goals have come in the first-half of Premier League games this season. The Swans have only kept two clean sheets in their last 15 top-flight matches. Manchester United Seven of the 14 goals Manchester United have conceded away from home in this season's Premier League have been headers. The Red Devils have kept just one clean sheet in their last 10 Premier League matches. Robin van Persie has scored 60 goals in his 72 Premier League appearances since the start of 2011. Wayne Rooney has seven goals and seven assists in 13 Premier League appearances this season. According to Opta statistics, Manchester United were the only side to have over 50% possession against Swansea both home and away in last season's Premier League.
