Didier Drogba came back to haunt Arsene Wenger's Arsenal as his late brace gifted Galatasaray the Emirates Cup at the expense of the home team.
The Ivorian scored a ruthless 13 goals in 14 games against Arsenal whilst at Chelsea and Wenger will be rueing his decision to invite him back to the ground he did so much damage on.
A penalty, along with an emphatic strike in the closing five minutes sealed a comeback for the Turkish side who left Arsenal without a win in their own tournament.
Arsene Wenger handed a starting place to their only signing of the summer Yaya Sanogo in an otherwise full strength Gunners team.
An unexpected weight of pressure had been added to Sanogo's shoulders with Arsenal's inability to add a more reputable striker to the team.
The young Frenchman, who joined on a free transfer from Auxerre, impressed from the first minute however, as he immediately won the ball in the final third before neat footwork gave him the opportunity to shoot.
His tame shot was easily stopped by Fernando Muslera but the early signs were promising.
A second opportunity went by for Arsenal - this time for last season's top scorer Theo Walcott - when Aaron Ramsey fed a superb ball over the top of the Galatasaray back four to release the England international.
With just the goalkeeper to beat, Walcott chipped the ball only to see it drop wide of the post.
With Galatasaray growing in to the game and the pace dropping, the pressure was on Arsenal to appease a home crowd that seemed on the verge of boredom.
That relief came with five minutes to go in the first half after Walcott's cross drifted past a sea of players, dumbfounding Muslera and finding the back of the net.
A 1-0 win would be enough to see Arsenal lift the Emirates Cup but with Drogba leading an increasingly dangerous looking Galatasaray front-line, it seemed another goal would be needed if Arsenal were going to win.
Those suspicions were proved correct when substitute Ignasi Miquel fouled Drogba in the box to gift Galatasaray the sixth, and probably softest, penalty of the tournament.
Only one man was going to take it - Drogba stepped up to equalise from the spot, sending Szczesny the wrong way.
Sensing the fragility of Arsenal's back four, Galatasaray and Drogba continued to press forward in search of a winner.
And it was left up to an inspire Drogba to score it. A good ball from Wesley Sneijder was expertly controlled from Drogba, who finished emphatically to make it 2-1, making mincemeat of Per Mertesacker in the process.
The defeat leaves Arsenal third in the table just ahead of Napoli on goal difference.
