Form guide: The Reds are unbeaten in the last eight league games and won both festive fixtures at Old Trafford (4-3 v Newcastle, 2-0 v West Brom).

Betting: Given the sides' form, it's no surprise to see United as heavy 53/100 favourites with bwin. Wigan are 5/1 to notch a home win, while the draw is priced at 3/1. If you fancy a Reds romp you can get 17/1 on United winning 4-0 and 3/1 on Robin van Persie scoring the first goal of the game.
Ins and outs: Sir Alex will inevitably shuffle his pack for what is the Reds' fourth game in 10 days. Wayne Rooney, Anderson and Nani are out through injury, although Rafael and Phil Jones are likely to return. Shinji Kagawa played against West Brom after a long break, while Robin van Persie, Javier Hernandez, Paul Scholes and Ryan Giggs should all be fresh after being rested against the Baggies.

Last meeting: United beat Wigan 4-0 at Old Trafford back in September in a game that featured goals by debutants Alexander Büttner and Nick Powell. The last time at Wigan was a different story, however. The Latics won 1-0 that night, a
