Mark Chapman introduces highlights of the day's two Premier League matches. It is the first Manchester derby of the season, with the managers of both United and City getting their first taste of this unique rivalry. David Moyes will be used to the intensity of such games, having overseen plenty of Merseyside derbies in his time as Everton manager. However, the Scot had a poor record in those clashes, and will be hoping for a change of fortunes now he is at Manchester United. His opposite number, Manuel Pellegrino, was sacked after just a season at Real Madrid - in part because his side finished behind arch-rivals Barcelona - so the Chilean also understands the importance of getting the better of big rivals. In the day's early kick-off, Arsenal host Stoke, hoping to extend their perfect home record in Premier League fixtures against the Potters, having won on all five previous occasions. Could new Stoke manager Mark Hughes inspire his side to end their losing streak?
