In the league round, we can see the difference between these two teams when they were in the Champions League, yes Liverpool is in 1st place and Paris Saint Germain is in 15th place, even if they were unsuccessful in the last 3 matches at that time, they would have been eliminated early. But luckily they were able to win in a row after they got a series of defeats.
I don't mean to underestimate Paris Saint Germain at all, it's just that I judge and make predictions based on their performance statistics.
If you predict from the results of their performance statistics, actually positions 1 and 15 are not a problem. And if we really look at the performance statistics of both teams, you can see from the GF and GA that both teams have. Liverpool managed to score 17 goals and conceded 5 goals. While PSG managed to score 14 goals and conceded 9 goals during the group stage. From the results of these statistics, both are not much different and almost have the same performance. It's just that Liverpool is favored because it is more popular and more experienced in terms of reaching the final round.
