Group B: Montpellier 1 Arsenal 2

Arsenal got its UEFA Champions League campaign off to a winning start after coming from behind to beat Montpellier 2-1 in France.

Manager Arsene Wenger, serving the first of his three-game touchline UEFA ban, would have been fuming from the stands when Thomas Vermaelen gave away an early penalty, although replays suggested the foul was probably just outside the box.

However, the Premier League club - coached by assistant boss Steve Bould from the sidelines for the first time - responded magnificently and was soon level through a fine finish by Lukas Podolski.

Before the French side, making its Champions League debut after last season's brilliant Ligue 1 campaign, could recover, Arsenal swept ahead on 18 minutes through Gervinho.

Although the host rallied after the break, with lively winger Remi Cabella hitting the crossbar and goalscorer Younes Belhanda missing a great chance late on when he fired straight at stand-in goalkeeper Vito Mannone, the Gunners closed out a battling victory.

Combative midfielder Abou Diaby had only just returned from injury to the starting XI - and went straight into the referee's notebook inside the first minute when he clattered Marco Estrada.

Arsenal settled well, and soon had the host on the back foot.

However, Montpellier remained dangerous on the counter-attack - and took a somewhat controversial lead on nine minutes.

Gunners captain Vermaelen slid in on Belhanda at the far right edge of the penalty area, and the Moroccan went down in a heap. However, the assistant on the goal line indicated the foul was inside the box - much to the disbelief of the visitor.

Belhanda got up to take the spot-kick himself, netting Montpellier's first Champions League goal with a nonchalant chip.

Arsenal responded well to trailing for the first time this season - and was behind for less than 10 minutes.

Northern summer signings Santi Cazorla and Olivier Giroud, playing against his old club, combined with some slick passing on the edge of the Montpellier area to slip Podolski clear - and the German tucked the ball under goalkeeper Geoffrey Jourdren.

Before the home side could regroup, Arsenal struck again on 18 minutes.

This time the damage was done down the right, as the ball was recycled quickly through Gervinho and Giroud out to fullback Carl Jenkinson, who darted toward the line before cutting the ball back across the six-yard box - where Gervinho arrived on cue to bundle in it.

To its credit, Rene Girard's side - which battled against the odds to beat big-spending Paris Saint-Germain to the championship last season - refused to lie down and slowly built up some momentum again.

In the 33rd minute, Argentina forward Estrada - brought in to offset the departure of Giroud - made space for a shot from 20 yards, which Mannone tipped around the post.

Arsenal, though, continued to look menacing through its quick breaks.

As half-time approached, Giroud, who struck 21 goals for Montpellier last season, swept wide after Kieran Gibbs crossed from the left.

Arsenal, though, was almost caught out after the restart when Diaby dithered on the ball inside his own area and was robbed by Cabella, who slammed a shot just wide of the angle.

Montpellier continued to make the most of its dominant spell, as Arsenal was guilty of some stray passing when out to break up possession.

Cabella remained the dangerman, and 10 minutes into the second half he clipped a delightful 20-yard chip against the crossbar.

Diaby then surged through the Montpellier side and played in Cazorla, whose angled drive was beaten behind by the keeper.

Arsenal appeared to have weathered most of the home side's storm.

With 15 minutes left, Giroud was replaced by Aaron Ramsey. The France international left the field to general applause, although there were some boos around the unforgiving Stade de la Mosson.

Belhanda spurned a golden opportunity to level with 10 minutes left when some quick footwork sidestepped Per Mertesacker after a cross into the Arsenal box from the right, but he then fired straight at Mannone.
