Highlights and analysis of the day's two Premier League matches, plus a round-up of the weekend's earlier action, introduced by Mark Chapman. Champions Chelsea are unbeaten in the Premier League against last season's runners-up Manchester City since Jose Mourinho returned to the west London club. Mourinho will be looking to extend that run to five games, and with it steal an early march in the fledgling title race. Crystal Palace invested heavily in new signings over the summer, including one-time Arsenal target Yohan Cabaye. The Eagles' new arrivals are sure of a warm reception from the Selhurst Park faithful ahead of their home league debuts as Arsene Wenger's Gunners make the short trip across London.
