Mark Chapman and guests discuss the talking points from Saturday's Premier League matches and look ahead to Sunday's two fixtures. Defending champions Manchester City host Arsenal at the Etihad Stadium in the pick of the day's games, with Manuel Pellegrini's side unbeaten in five league meetings against the Gunners. West Ham have been one of the surprise packages this season, and they hope to continue their early-season promise when they host Hull in the lunchtime kick-off.
