Champions Manchester United shook off their midweek defeat at Burnley with an emphatic 5-0 away win at Wigan Athletic in the Premier League on Saturday.

After a low-key first half Wayne Rooney scored twice to reach 100 goals for United while summer signing Michael Owen opened his account for the club late on and Nani completed the rout.

Abou Diaby helped free-scoring Arsenal to the top of the embryonic table, scoring twice in a 4-1 home defeat of struggling Portsmouth to take the Gunners' goal tally to 10 in their opening two matches.

Manchester City joined Arsenal and United on six points with 1-0 home win against Wolverhampton Wanderers while Sunderland also earned their second win of the season, coming back from a goal behind to beat Blackburn Rovers 2-1.

Hull City beat Bolton Wanderers 1-0 while Birmingham City and Stoke City ended 0-0 - the first draw of the new Premier League season.
