Highlights from the opening Premier League matches of the new calendar year, including two London derbies - Arsenal v West Ham United at the Emirates Stadium and Fulham v Chelsea at Craven Cottage. The Gunners had Robin van Persie to thank for three points in the Upton Park meeting between the sides in September, as he scored the only goal in a 1-0 win. The Cottagers were among the benefactors of the Blues' poor early season form as they claimed a point in a 0-0 draw at Stamford Bridge, which they will hope to build upon in this reverse fixture. Plus, action from Aston Villa v Tottenham Hotspur and Manchester United v Birmingham City.
