Manchester United continued its perfect start to the season with a spectacular 8-2 win over an increasingly beleaguered Arsenal side at Old Trafford.

A Wayne Rooney hat-trick and a brace for Ashley Young, as well as strikes for Danny Welbeck, Nani and Park Ji-Sung, exemplified the gulf in class between the two sides. Theo Walcott and Robin van Persie replied with strikes worthy of mere consolation.
