Mark Chapman introduces highlights of the day's three Premier League matches, including two mouthwatering derbies, with Liverpool hosting Manchester United and Arsenal in action against north London rivals Tottenham. The rivalry between Liverpool and Manchester United, England's two most successful clubs, ensures games between the two north west teams are always fiercely competitive. But today's fixture has an added edge following United's recruitment of manager David Moyes, who has arrived after 11 years in charge of Liverpool's cross-city rivals Everton. The Scot never won a game at Anfield while in charge of the Toffees, and will want to put that record right with his new club. Derby matches can sometimes be cagey affairs, but games between Arsenal and Tottenham invariably produce entertainment. The previous six meetings have yielded a total of 31 goals - including 5-2 wins for Arsenal in the previous two matches at the Emirates.
