Giroud treble inspires rampant Arsenal to reach last 16

ATHENS: Olivier Giroud grabbed a superb hat-trick as Arsenal crushed Olympiakos Piraeus 3-0 to book their spot in the Champions League's last 16 with a classy demolition job that ended the hopes of their Greek opponents on Wednesday.

With Arsenal needing an emphatic victory to make it out of Group F, France forward Giroud produced a high-calibre display to ensure the English club finished second, level on nine points with Olympiakos, but ahead by virtue of their better head-to-head record.

Giroud opened the scoring in Greece with a powerful header in the first half, doubled Arsenal's advantage with a calm left-footed finish quickly after the restart and rounded off a superb individual display with a penalty.

The victory completed a remarkable turnaround in fortunes for Arsenal who lost three of their first four games of the campaign and needed to win by any result other than 1-0 or 2-1 in their decisive group clash to finish second behind group winners Bayern Munich.

"I told you before that it would be the greatest escape," Arsenal manager Arsene Wenger said.

"I must say I'm very proud of the team as we had to be right on the mental and tactical side."

In what was a straight shootout for the second spot in the group at the Georgios Karaiskakis stadium, Giroud opened the scoring with a stooping header from Aaron Ramsey’s cross just before the half-hour.

Olympiakos responded to going behind positively, however, and finished the first half stronger. Felipe Pardo’s cross was deflected over by Laurent Koscielny and Arthur Masuaku tested Arsenal keeper Petr Cech with a long-range drive.

Arsenal grabbed the vital second goal shortly after the restart as Giroud benefitted from Joel Campbell’s trickery to latch onto the Costa Rica forward’s neat pass and side-foot past Olympiakos keeper Roberto four minutes after halftime.

While Arsenal controlled possession, they looked vulnerable at times on the break and the hosts almost hit back immediately.

An unmarked Manuel Da Costa headed a corner straight at Cech, who shortly afterwards made a superb flying save to deny the impressive Kostas Fortounis.

Any hope of a comeback from the hosts though was extinguished when Italian referee Nicola Rizzoli awarded a penalty against Omar Elabdellaoui for handling Nacho Monreal’s shot, with Giroud sending Roberto the wrong way from the spot.

The win preserved Arsenal’s superb record in the Champions League, having now qualified for the competition's second stage for the 16th time in succession.

Olympiakos coach Marco Silva was understandably deflated but gracious in defeat.

“We were eliminated simply because Arsenal were better; they showed their level tonight and we just couldn’t make it despite a massive effort,” said the 38-year-old, whose side will now play in the continent's second tier Europa League.

“Our fans should be proud though... the team gave all they had and it’s significant that we were in with a chance of qualifying for the second stage in the last round of group matches.”
