Danny Welbeck scored his first professional hat-trick as 10-man Arsenal swept aside Galatasaray in the Champions League.
The England striker, excellent throughout, stabbed in a first-half opener before side-footing in a second.
Burak Yilmaz scored a penalty after Arsenal goalkeeper Wojciech Szczesny was sent off for a foul, but it was to be nothing more than a consolation.
The win was Arsenal's first in this year's Champions League and means they have three points in Group D.
It was also the perfect way for manager Arsene Wenger to mark 18 years to the day since he was appointed Arsenal boss, and the Frenchman certainly deserves credit for naming an attack-minded side.
With Welbeck playing in his favoured central role and the former Manchester United striker ably supported by the pace and creativity of Sanchez, Mesut Ozil and Alex Oxlade-Chamberlain, the Gunners simply had too much for a Galatasaray side who have now failed to win in 10 visits to English sides
