I wouldn't cancel PSG so fast for just a 1 goal deficit considering how domineering they were against Liverpool in the first leg which has nothing to do with their home advantage in France and that's exactly or similarly how the atmosphere is going to be today at Anfield. If Liverpool doesn't improve from what they played at the. Parc des Princes then PSG could be making sure to correct their mistakes of not scoring a goal in the first leg after such an outstanding 90 minutes performance. In my view the hopes for both sides are  still 50/50 and it's likely today's game is going to get to extra time.
