Partizan Belgrade 1 Arsenal 3: Arsenal midfielder Jack Wilshere praised goalkeeper Lukasz Fabianski as the Gunners claimed a 3-1 Champions League win away to Partizan Belgrade.
The Pole, in for the injured Manuel Almunia, saved a second-half penalty to help Arsene Wenger's men record a second win in the group.
“It's been hard for our 'keepers at the moment and that was a great response from him,” Wilshere said.
“He made a good save at the end as well. Fair play to him.”
Goals from Andrey Arshavi Marouane Chamakh and Sebastien Squillaci secured victory for Arsene Wenger’s men who were forced to change in the dark because of a power failure.
“We had to use phone torches,” admitted Wilshere, but the Gunners came through that and an intense atmosphere during the opening exchanges to maintain their 100 per cent record.
Arsenal, who had six changes from the side beaten by West Brom at home on Saturday, went ahead in the 15th minute through Arshavin.
However, after wasting several more chances, the visitors were made to pay when Brazil-born striker Cleo levelled from the penalty spot after a handball by Denilson.
Partizan then had Marko Jovanovic sent off for hauling down Chamakh on 55 minutes, but Arshavin missed his penalty. However, Moroccan striker Chamakh and Squillaci secured victory — with stand-in keeper Fabianski saving a late spot-kick.
The Gunners, playing in yellow, made a positive start, as Wilshere was pressed up in support of lone frontman Chamakh.
The home fans, though, were screaming for a penalty when Pierre Boya went down under a challenge from Johan Djourou, but German referee Wolfgang Stark was having none of it.
Cleo then tripped over as he got clear into the left side of the Arsenal box, with Denilson sliding in to make a saving tackle as Nemanja Tomic looked to capitalise on the loose ball.
Fabianski needed two attempts to gather a hesitant header back to him from Squillaci as Boya looked to nip in on goal.
Cleo was lively, dispossessing Djourou on the right before cutting in to blast over from 20 yards.
However, the home side were stunned on 15 minutes as Arsenal snatched the lead.
Wilshere charged at the defence and when his path was blocked, the England youngster had the
presence of mind to back-heel the ball into the path of Arshavin, who drilled his shot into the bottom corner.
The Russian almost grabbed a second when put into the penalty area, but Partizan goalkeeper Vladimir Stojkovic was out quickly. Stojkovic denied Tomas Rosicky, before Jovanovic cleared Arshavin's goal-bound chip.
Arsenal paid the penalty for missing so many chances though when Denilson needlessly stuck his arm out as Radosav Petrovic delivered the ball into the box after half an hour.
Cleo sent Fabianski — in for the injured Manuel Almunia — the wrong way to level.
Arsenal had an early chance at the start of the second half following a driving run by Alex Song,
with the ball breaking to Rosicky on the right and his angled drive was well held by the goalkeeper.
Partizan were reduced to 10 men in the 56th minute when Jovanovic was shown a red card for tripping Chamakh as the Moroccan latched onto Arshavin's through ball.
Arshavin took the penalty himself — only to blast it straight at the goalkeeper.
On 69 minutes, the lively Arshavin was again denied, this time when Stojkovic made a good stop at the near post.
Moments later, though, and it was 2-1. Rosicky floated the ball and Chamakh headed goalwards. Stojkovic touched the ball onto the crossbar but the Arsenal striker was first to the rebound, nodding the ball into an empty net.
With eight minutes left, Squillaci headed in a corner from substitute Samir Nasri to make it 3-1.
There was late drama, though, when Kieran Gibbs was adjudged to have tripped Ivan Stevanovic in the penalty area, but this time Fabianski produced a brilliant save to deny Cleo.
The Pole then capped a confident display with another acrobatic stop from Ivica Iliev as the game headed for a close.
