Bayer Leverkusen travelled to the capital of France in hope of one of the greatest Champions League comebacks in history.
Unfortunately, despite an early goal they didn't do enough to turn around the 4-0 deficit from the first-leg and went down once again to the French champions, leaving the score 6-1 on aggregate.
Despite reported heavy interest from Liverpool, Schalke confirmed the signing of Sam in the January, confirming the German international would join the club in the summer.
Upon winning the player's signature, Schalke's sporting director Horst Heldt said: 'Sidney Sam had proven that he can be a dynamic addition to an attack even before his strong performances this season. He is versatile, ambitious and wants to achieve a lot with Schalke. We are delighted that he has opted for the Royal Blues.'
His goal against Paris Saint-Germain proved to be a taster for what Schalke fans can expect to come, and for Liverpool fans what they've missed out on.
Not usually known for his aerial ability, he did fantastically well to out jump highly-rated young centre-back Marquinhos to score and at least give the German club a little hope, even if only for a few minutes.
Scorned centre-back Marquinhos scored the equaliser seven-minutes later and sent Paris Saint-Germain on their way to the next stage of the competition. It was Lavezzi who eventually hit the winner on the night, sending the club through with a healthy aggregate lead.
