Arsenal 4 - 1 Galatasaray: Arsenal demolish Galatasaray with Welbeck treble

Arsenal ignited their Champions League campaign with a 4-1 thrashing of a feeble Galatasaray side on Wednesday with Danny Welbeck grabbing a hat-trick in a largely one-sided Group D clash in north London.

Galatasaray had never won in nine previous visits to England, and once Welbeck had punished them twice in the first half-hour their resistance crumbled, with Alexis Sanchez ending the match as a contest with Arsenal's third goal before half-time.
