Zlatan Ibrahimovic's injury against Chelsea will cost him at least four weeks on the treatment table, which rules him out of the second leg against Chelsea and likely through the semifinals, should PSG make it that far.
This piece of news significantly takes the shine off PSG's signature victory, which they hope will announce their arrival as European powers for years to come.
However, they proved their quality without Ibrahimovic in the half-hour he was off the pitch, and they are as well-equipped as anyone to deal with an injury to their star player.
With Ezequiel Lavezzi and Lucas Moura shining against Chelsea, and Edinson Cavani a member of the squad, the attack should be fine for the next month as Ibra recovers.
Most impressive has been the form of the midfielders. Marco Verratti has developed well, Blaise Matuidi has become the fulcrum of the side, and Thiago Motta has been as steady as ever. With Yohan Cabaye serving as an able deputy off the bench, PSG boast enviable depth and quality throughout the side.
Firm favorites following the victory in Paris, PSG will aim to get an early away goal and kill off the tie as they focus on wrapping up another domestic championship. The ultimate goal of owner Nasser Al-Khelaifi has been to create a team that is capable of competing with the Real Madrids and Bayern Munichs of the world, and PSG are awfully close to reaching that point.
Should they advance, PSG will not be a desired opponent of any of the other three sides remaining. Of course, all four teams will be of extremely high-quality after making it the semifinals, but PSG will be hungry to prove their worth over two legs against a top side.
They may be hoping to draw Real or Bayern in an effort to show the world their ultimate arrival against one of the legendary clubs. Unfortunately, the loss of Ibra will hurt against those sides, as his individual ability can swing a tie.
Again, PSG proved against Chelsea they are a force on the world stage. The onus will be on them as likely underdogs in the semifinals to continue to prove their progress.
