Didier Drogba continued to haunt Arsenal as he bagged a late double in Galatasaray's 2-1 Emirates Cup triumph on Sunday.
The former Chelsea striker came off the bench at the break and cancelled out Theo Walcott's opener with a penalty in the 79th minute at the Emirates Stadium.
More was to come from Drogba though, as he latched on to a Wesley Sneijder through ball and beat Arsenal's Per Mertesacker with an excellent first touch with just two minutes to play.
Drogba then lashed a left-foot effort into the top-right corner, taking his record against Arsenal to 15 goals in as many matches as the Turkish Super Lig outfit claimed a smash-and-grab victory.
Galatasaray - who beat Porto 1-0 on Saturday - won the Emirates Cup as a result.
Arsenal manager Arsene Wenger handed the club's sole signing in the transfer window so far - French forward Yaya Sanogo - a start, while Walcott and Santi Cazorla were also involved from the beginning.
Former Arsenal midfielder Emmanuel Eboue was picked as Galatasaray captain, but stars Drogba and Sneijder began on the bench for the visitors.
Sanogo almost scored within the first minute of his maiden Arsenal appearance, as he capitalised on a defensive error before thrashing a low effort at Galatasaray goalkeeper Fernando Muslera.
Muslera made a good save and was again called in to action to deny Sanogo shortly after, while Arsenal had penalty appeals waived away after Aaron Ramsey went down under the attention of Eboue.
Johan Elmander had Galatasaray's first effort of the day in the 16th minute but scuffed his shot while Walcott somehow missed everything after an excellent long pass from Ramsey sent him through on goal.
Walcott fired Arsenal in front five minutes before the break though, as his cross from the left floated into the back of the net with Muslera stranded.
Sanogo had two more efforts on goal as Arsenal took a deserved lead into half time but Galatasaray responded by introducing Drogba and Sneijder.
Drogba's first effort on goal was a waste, shooting from an impossible angle, but he fired a warning shot when he forced Szczesny into a good save on the hour-mark.
Arsenal substitute Olivier Giroud had two attempts saved shortly after coming on but the visitors won a penalty after Drogba went down easily following a challenge from Miquel.
And Drogba dispatched the spot-kick with ease before bagging a dramatic winner to disappoint the Arsenal fans.
