Hull City secured a stunning 2-1 win at Arsenal in the English Premier League on Saturday thanks to a header by Daniel Cousin that ruined Arsene Wenger's 12th anniversary as manager of the north London side.
It was only Arsenal's second defeat in 60 matches at the Emirates Stadium and meant they tumbled from first place at the start of the day into fourth spot. Hull, who are playing in the top division for the first time, are sixth.
Arsenal, who dominated the first half, went ahead after a scrambled own goal came off Paul McShane in the 50th minute, but Hull hit back with an awesome strike from Geovanni after 62 minutes and Cousin's header from a corner in the 66th.
The shock result meant Chelsea stayed top with 14 points from six matches, the same number of points as Liverpool but with a better goal difference. Aston Villa, who beat Sunderland 2-1, were third with 13 points and Arsenal fourth with 12.
Chelsea and Liverpool maintained their unbeaten starts to the season with 2-0 away wins earlier on Saturday.
Goals from Jose Bosingwa and Nicolas Anelka gave Chelsea victory at Stoke City while Liverpool beat Everton by the same score in the Merseyside derby at Goodison Park with two goals from Fernando Torres.
Champions Manchester United also won 2-0, beating Bolton Wanderers at Old Trafford where a debatable penalty from Cristiano Ronaldo and a second goal from substitute Wayne Rooney gave United victory.
