Colin Murray introduces highlights of the day's four Premier League games. Norwich travel to the Stadium of Light looking to complete the double over Sunderland, having beaten the Black Cats 2-1 in early December during a stunning run of form that saw them go ten matches unbeaten. Meanwhile, struggling Wigan have pulled off some great escapes to avoid relegation over the last few seasons and this one looks like it will require the same. They host Newcastle, and will be encouraged by a good recent home record against the Toon. There are also two London derby games as Chelsea meet West Ham at Stamford Bridge and Tottenham face Fulham at White Hart Lane.
