Tonight's match at Parc des Princes was a riveting affair between two of the games financial superpowers.
Chelsea, who have long since embraced the riches Roman Abramovich brought in when he took over the club were visiting Paris Saint-Germain, getting more and more comfortable in their own opulent surroundings.
And with plenty of of multi-million pound transfer signings on show, it was inevitable that someone would come forward and do something tremendous.
But not many people would have predicted that Javier Pastore, warming the bench until the 85th minute and without a goal to his name all season, would be the man to deliver it. Though, thinking about it, he did cost €40 million.
It wasn't just the fantastic skill the Argentine displayed, as he slalomed through the Chelsea defence in the 92nd minute of the match before rifling a shot low past Petr Cech's near-post, it was the fact that the strike turned a narrow 2-1 win for PSG into a 3-1 victory over the Blues.
It provided the cushion that Chelsea would have to win by two clear goals in next week's return leg at Stamford Bridge.
And with the attacking talent on display for the French champions, who's to say they won't score an away goal or two of their own.
