Mounier is replaced by Karim Ait-Fana as Montpellier make a change.

The main issue I have with the 'I am Vito Mannone' chant is the next line - surely there's plenty of people you'd rather be than the Arsenal substitute 'keeper. If not there should be. I'd rather be Wojciech Szczesny for a start.
James Ellis also says: "The song Arsenal fans are trying to get going is "I am vito mannone!!!" to the chesney hawkes number I am the one and only." Thanks James, it could be better though. In my opinion the Emirates faithful clearly need to check out the Roy Orbison smash hit.
Scott Armstrong comments on the big issue from the first half: "I am Vito Mannone" to the tune of Chesney Hawkes "I Am The One And Only." Good one Scott, very good. Although I will have the one-hit wonder in my head all night now... 'There ain't nobody I'd rather be.'

Arteta hesitates when the short free-kick is passed to him and Montpellier block his cross.
Giroud shows strength to win a free-kick for Arsenal.

Montpellier look a little-bit shell-shocked after the quickfire blitz from Arsenal.
GERVINHO! It's the Jenkinson and Gervinho combination once again as the right-back fires in a devilish low cross and Gervinho just cannot miss from five yards out. 2-1 Arsenal, what a response from the Premier League outfit.
PODOLSKI!. Lovely move from Arsenal that ends with a neat little flick-pass from Giroud to Lukas Podolski and the German does not waste chances like that. 1-1.
