What a night for Arsenal! What a night for Olivier Giroud!
Often derided as not being good enough to lead a top class team, Giroud came up trumps for the Gunners when they needed him most in the Champions League.
Giroud put Arsenal in from against Olympiakos with a header from an Aaron Ramsey cross in the first half.
After the break the French international doubled his tally following a sublime assist from Joel Campbell.
Giroud rounded off his hat-trick with a coolly taken penalty.
Watch Olivier Giroud’s first ever Arsenal hat-trick v Olympiakos below.
