This game was seen as the first major test that either side had faced so far this season, with both teams winning all of their league games so far.
However, it was Jurgen Klopp's Liverpool side who came out on top, despite the likes of Kylian Mbappe and Neymar making the away side the favourites in many people's eyes.
Speaking after the game to 'BT Sport', former Man Utd defender Rio Ferdinand revealed how bad he thought the performance was from the French champions.
"Liverpool were much what we expected. The energy, the intensity in which they played with, attacking at every moment but the Paris Saint-Germain team, I'll be honest with you, I was very very disappointed in them." the winner of the 2007/08 Champions League said.
"As individuals, collectively, there was zero intensity. Complete opposite scale to the Liverpool team. For me at times, it looked like they were in a testimonial game the way they played. The forwards never wanted to defend, I don't know if they are not asked to or they just don't want to and they got punished.
"You come to Anfield, 11 players need to perform and today this Liverpool team outperformed and outworked this Paris Saint-Germain team. They have built a superstar team, they have got superstar players but I don't see them as a team."
