Mark Chapman introduces highlights of the day's two heavyweight fixtures in the Premier League: Arsenal v Manchester City, and Manchester United v Liverpool. Games between Arsenal and City and have been tight, low-scoring affairs in recent seasons and last year's corresponding fixture at the Emirates was no exception, with Gunners midfielder Mikel Arteta scoring the only goal three minutes from the end. At Old Trafford, Manchester United will be vying to complete the double over Liverpool, having beaten their great rivals at Anfield in September courtesy of Robin van Persie's late penalty.
