Colin Murray introduces highlights from the day's Premier League matches. Chelsea travel to Manchester United looking to make amends for what has been a disappointing season for the Blues, who claimed a league and cup double last season. Victory at Old Trafford would be some comfort after Sir Alex Ferguson's side knocked them out of the Champions League. It is always a big game when Wolves play West Brom, and with both sides in the relegation battle, there will be even more riding on the match at Molineux. The day's other game sees Arsenal visit Stoke, where the Gunners left it very late for victory last season in a game marred by a serious injury to Aaron Ramsey.
