Wenger aims to step it up a gear

FC Thun 0 Arsenal 1

The Gunners went into the clash in Berne safe in the knowledge they had already made sure of place in the last 16 following four straight wins.

And they eventually wrapped up another three points following an 87th-minute penalty from substitute Robert Pires after Robin van Persie had been pulled back by Selver Hodzic, the referee pointing to the spot following the intervention of his assistant.
