Arsenal's miserable start to the Premier League season continued yesterday as two second-half own goals handed Blackburn an upset 4-3 victory at Ewood Park.

Arsenal, looking to build on their unconvincing 1-0 win over Swansea last week, appeared on course for victory in the first half when they went ahead twice with goals from Gervinho and Mikel Arteta.

But the Gunners' defensive problems returned as two goals from Ayegbeni Yakubu and own goals from Alex Song and Laurent Koscielny put Blackburn 4-2 up.

Marouane Chamakh, on as a substitute, ensured a nervous finish when he headed in Robin van Persie's cross to pull one back for Arsenal on 85 minutes, but the home side hung on for their first win of the season.

It leaves Arsenal with four points and eight behind leaders Manchester United, who face Chelsea today.

Afterwards beleaguered Arsenal boss Arsene Wenger said his side were still suffering a psychological hangover from their 8-2 drubbing by United at Old Trafford last month.

"At the moment defensively we are fragile because our confidence is gone due to what happened at Old Trafford," Wenger said. "It's terrible. It's just not good enough and of course we are very frustrated."

Victory was sweet for Rovers boss Steve Kean, who has faced calls for his sacking from disgruntled Blackburn fans. About 250 Rovers supporters marched to Ewood Park before kick-off to call for his dismissal but he said he believed the win would keep his critics at bay.

None of the top three teams in the league played yesterday, with leaders Manchester United entertaining Chelsea today. Manchester City travel to Fulham, while Liverpool face Tottenham at White Hart Lane.

The promoted sides - Queens Park Rangers, Swansea and Norwich - all won.

QPR's resurgence since their takeover by Malaysian tycoon Tony Fernandes continued with a 3-0 win at Wolves, where goals in the opening 10 minutes from captain Joey Barton and Alejandro Faurlin put the Hoops 2-0 up. DJ Campbell completed the scoring late on.

Swansea scored their first win of the season - and their first in the top flight since 1983 - after downing West Bromwich Albion 3-0 at the Liberty Stadium. Scott Sinclair, Leroy Lita and Nathan Dyer scored for the Swans.

Norwich also registered their first win of the campaign, goals from Anthony Pilkington and Bradley Johnson setting up a 2-1 win over Bolton at the Reebok.

Wanderers had Ivan Klasnic sent off for head-butting Marc Tierney on half-time. Martin Petrov pulled a goal back for Bolton on 64 minutes but the Canaries held on.

Newcastle moved into fourth after holding Aston Villa to a 1-1 draw at Villa Park, Leon Best's second-half strike securing a share of the points for the Magpies after Gabriel Agbonlahor had put the home side ahead.

Everton came from behind to down Wigan 3-1 at Goodison Park, Phil Jagielka equalising Franco Di Santo's opener for the Latics before substitute Apostolos Vellios made it 2-1 on 84 minutes. New loan signing Roysten Drenthe added a third deep into injury time.
