Dan Walker and guests look ahead to the weekend's football fixtures, with the first of seven Premier League matches today beginning at lunchtime when the reigning champions Manchester City host Tottenham at the Etihad Stadium. Spurs will be hoping to fare better than they did last season when they were thrashed 6-0 by City. Elsewhere, there's a London derby as Crystal Palace welcome Chelsea to Selhurst Park. This fixture last season saw Palace boost their survival hopes with a shock 1-0 victory over league leaders Chelsea - courtesy of an own goal from John Terry.
