Spanish player Jose Reyes scored the winner goal to help Arsenal snap a three-game losing streak in the English Premiership with a 1-0 win over an improved Charlton side on Monday.
Reyes slotted in from point-blank range at the time Thierry Henry's angled shot fell into his path off keeper Thomas Myhre.
The goalkeeper had earlier saved a Freddie Ljungberg strike and a header from Henry, while Charlton's Darren Bent was denied after a last-ditch Sol Campbell tackle.
Charlton had to handle then Danny Murphy's 72nd-minute dismissal. Their Coach Alan Curbishley had taken out his anger over his side's recent dip in form by making six changes - and the move seemed to have paid dividends early on.
The home club picked up the pace after a careful start to the game and midfield playmaker Murphy showed why he had survived the Addicks axe.
Central defender Sol Campbell was a commanding for Arsenal
In a five one-touch passes released Ljungberg only for the hesitant Swede to see his shot blocked by keeper Myhre when he had acres of space and plenty of time to pick his spot.
Arsenal were also denied when Myhre managed to get a hand to a glanced, first-time Henry header as the Frenchman raced on to Lauren's long ball.
Charlton's work ethic had earned them enough good fortune to stay on level terms - and they almost earned the lead on the stroke of half-time.
Darren Bent raced clear on to a Shaun Bartlett ball and was set to pull the trigger before a lunging, last-ditch tackle from Campbell denied him a shot.
Arsenal burst out of the blocks after the interval and their pressure was rewarded when Henry's angled shot was saved by Myhre only for the ball to fall into the path of Reyes, who slotted home from close range.
Charlton had little response to an improved Arsenal and their task was made even harder when Murphy was harshly sent off for two bookable offences after throwing the ball to the ground.
Reyes almost make another to the visitors' lead but the one goal was enough as Arsenal secured only a second away win in the Premiership this season.
