#3 Neymar Jr.
Neymar didn't have a great start to the 2019-20 season, but since his return from injury, the Brazilian has been nothing short of brilliant for the French club. And against Borussia Dortmund, he will be expected to step up.
The 2014-15 Champions League winner has shown on many occasions what he can do on the big stage, and that he can be a nightmare for the opposition defense when the pressure is high.
He is one of the very few players in the world who doesn't need many touches to make an impact on the game. Neymar can produce moments of magic out of nothing, thanks to his dribbling skills, set-piece ability and quick decision-making.
As long as he is on the pitch, he will have an impact on the game against Dortmund.
#2 Kylian Mbappe
Kylian Mbappe had a very good time during the group stage as he was Paris Saint-Germain's best attacker by a mile. The young sensation has always been a threat for any opposition defense but when you have players like Neymar and Angel Di Maria to find your runs, the threat level just goes up a notch.
At 21 years of age, Mbappe has already played three full Champions League seasons, which is a testament to the kind of talent he possesses.
Having played and performed in such high-stakes matches, Mbappe is one of the most important players alongside Neymar who would be seen as potential match-winners for PSG this season.
