Goal-crazy Arsenal sink Columbia.

Arsenal went goal crazy on Tuesday night as they kicked off their European tour with a 7-1 demolition of SC Columbia in Vienna.

Nicklas Bendtner, Robin van Persie and Aaron Ramsey all grabbed braces, while William Gallas also got on the scoresheet.

The Gunners did suffer a minor embarrassment when a freakish goal from Patrick Lehner gave the amateurs a shock first-half lead after Manuel Almunia's clearance cannoned off him into the net.

That was met by a delighted record crowd of 6,900 at the Schwarzlackenau Stadium but it merely stung Arsenal into action.

Bendtner equalised within a minute and grabbed another after Ramsey had fired the visitors ahead.

Van Persie slotted home a penalty early in the second half and nodded in Bacary Sagna's cross to make it five and Gallas got in on the act before Ramsey fired in off a post late on.

Thomas Vermaelen started for Arsenal and he squandered a decent chance for his first Arsenal goal, lashing a shot wide after Ramsey's chip had fallen for him eight yards out.

Arsenal, who made eight changes at the break, travel across the border into Hungary for Monday's friendly at Szombathelyi.
