Olympiakos have not much luck in recent seasons in the Champions League, usually drawn against Arsenal in the group stages.
This time out it was different - and the Gunners have even leant them a helping hand in the form of Costa Rican sensation Joel Campbell.
The youngster who could dent England's World Cup hopes next summer turned in a Man of the Match performance as the Greek side squeezed through into the Champions League knockout rounds.
They needed to match Benfica's 2-1 win over an already-qualified PSG - and while opponents Anderlecht managed to have three men sent off, they made hard work of it.
Without injured striker Konstantinos Mitroglou, Argentine Javier Saviola was the man who stepped up to score the goals - but Joel Campbell stole the show.
Campbell was a threat throughout, completing seven successful dribbles - Anderlecht's whole team managed just nine by contrast.
He created three goalscoring opportunities, and had three shots on goal himself, worrying the Belgian's defence with his direct running.
His performance certainly gives further credence to the rave reviews he has been picking up.
He has 6 goals and 8 assists in 16 games in all competitions for Olympiakos this season, and is clearly maximising his experience to it's full potential.
After a promising spell with La Liga side Real Betis last season, a move to Greece at first looks like a step down. The fact he will be playing in the Champions League last 16 now proves that certainly is not the case.
