A goal from Lukas Podolski and a brace from Aaron Ramsey have given Arsenal a comfortable 3-0 lead over Galatasaray in their final Champions League Group D game.
Arsenal made a dream start as Podolski lashed the ball into the roof of the net from a tight angle in the third minute of the match to give the visitors an early 1-0 lead.
The hosts then had two chances to restore parity, but Hakan Balta flashed a shot wide of goal before Wesley Sneijder was denied by Wojciech Szczesny.
Sixty seconds after Szczesny's save, Ramsey put Arsenal two goals ahead with a calm finish into the bottom corner following a neat interchange with Alex Oxlade-Chamberlain and Podolski.
The German forward then rattled the crossbar with a powerful strike, and shortly afterwards Ramsey effectively put the game out of Galatasaray's reach with a thunderous half-volley from 25 yards which flew into the top corner.
