United's 65th and final game of 2009 is against Wigan, whose 10-game record against the Reds isn't much to write home about...
Form guide: Wigan are without a win in four matches after battling to a 1-1 home draw with Blackburn on Boxing Day, a result which leaves them hovering above the relegation zone. It's been a strange old first half of the season for the Latics, who have beaten Chelsea and Aston Villa and drawn with Manchester City, but suffered heavy defeats to Portsmouth and Tottenham – the latter that incredible 9-1 reversal last month.
United bounced back from the 3-0 setback at Fulham with a largely comfortable, if error-strewn, win at Hull on Sunday. The champions will be delighted that, despite an injury crisis and five defeats already, Chelsea are still within touching distance at the top. The record in all competitions between these two north-west rivals makes good reading for United, who have won all 10 previous encounters, scoring 30 goals and conceding just four. The Reds won 5-0 at the DW Stadium in August.
Ins and outs: Wigan, remarkably, have an almost entirely clean bill of health, with only Mohamed Diame (knee) on the sidelines. The outlook is looking brighter for United, who welcomed back defenders Nemanja Vidic, Wes Brown and Rafael against Hull and now have Gary Neville, Paul Scholes and Anderson available. Jonny Evans and Rio Ferdinand are not too far away, but Edwin van der Sar has been granted compassionate leave to be with his ill wife.
Star man: Hugo Rodallega hit Wigan's equaliser against Blackburn last week and is the Latics' top scorer with seven goals. Wigan are unbeaten in the six league matches in which the Colombian has scored. Although the Reds kept the frontman quiet in August, he will still be a handful on Wednesday with his pace and power.
Manager: Roberto Martinez's philosophy of free-flowing, attacking football has produced some mixed results this season, as we've already outlined. But he has also instilled some grit into his side: already this season they have bounced back from thumpings at Arsenal and Spurs with wins over Chelsea
