Overview:Gary Lineker introduces highlights and reaction to the day's six Premier League matches. High-flying Leicester City's home clash against Norwich City was one of the standout fixtures. The Foxes have been this season's surprise Premier League package and they look to continue their remarkable form against the Canaries at the King Power Stadium. In the lunchtime game, Sam Allardyce returned to his former employers West Ham. Allardyce left Upton Park last summer and, with new club Sunderland in relegation trouble, revenge would have tasted all the sweeter at his old stomping ground. Elsewhere, Chelsea travelled to Southampton, Stoke took on struggling Aston Villa, Watford faced Bournemouth at Vicarage Road and West Brom entertained Crystal Palace.
