Chelsea were dealt some major damage through the performance of Argentine Ezequiel Lavezzi, with the ex-Napoli player scoring one and setting up another.
Zlatan Ibrahimovic and Edison Cavani were the two much talked about players, and with good reason, with both boasting impressive records at their previous clubs and strong performances in France this year. The two are first and second in the Ligue 1 goalscoring chart, and fourth and sixth costliest transfers of all time.
The Swede cost Barcelona nearly €70 million when he signed from Inter in 2009, before ending up in Paris via a brief return to Serie A, while Cavani joined from Napoli for a cool €65 million at the start of this season.
Despite the focus on the two superstars it was another player that did the bulk of the damage to Chelsea's Champions League campaign.
Argentinian winger Ezequiel Lavezzi, who was linked to both Arsenal and Tottenham earlier in the season after a difficult beginning to his league campaign, shone at Parc des Princes on Wednesday, giving one of his best performances since moving to PSG for £25 million from Napoli in 2012.
Lavezzi scored an excellent goal, his tenth of the season, controlling a cross with his chest and lashing it into the top corner past Petr Cech. Few others can take credit for David Luiz's awkward own goal except the Brazilian himself, but the superb cross that created the confusion also came from the left foot of Lavezzi.
The performance may see a renewed interest in the winger from Arsenal and Spurs, who wouldn't have been put off by the damage he did to their London rivals. In fact his performance could even have convinced one of the two sides to step up their enquiries.
Besides the two goals, Lavezzi was a constant menace to the Chelsea defence with his work rate and close control, and next week's return leg at Stamford Bridge may well see him afforded added attention in terms of nullifying him - a task that may be easier in its proposal than its accomplishment.
