Honestly not trusting PSG, no way! Liverpool play much more different at Anfield. But it is your choice of course.
Yeah Liverpool plays differently in anfield but did you watch the last game

, Psg is actually capable of something different this time, the only advantage Liverpool has now is the anfield apart from that Psg is actually capable of taking them out.
Anyway, In about 48 hours everything will be determined, it will a elimination game so everywhere's going to be hot.. imo I don't trust Liverpool either, the immunity is beginning to wear off somehow ....
Arsenal, Aston Villa and Bayern Munich who won by two goals or more in the first leg can be more relaxed in the second leg, while Liverpool must remain wary of PSG surprise because their goal in coming to Anfield is to get a ticket to the quarter-finals.
Even though Liverpool have the advantage of playing at Anfield, this game is very decisive, a small mistake can punish them because PSG will try to continue to pressure Liverpool as they did in the first leg. In my opinion, this game will be more exciting than before because there will be one team that will be eliminated.
What Aston villa, Arsenal and Bayern Munich did was the best and it is always the best thing to do whenever you are playing, having victory in the first leg is always good because it will give you a little confident and some level of freedom and advantage most especially if the goal margin is from 2 and above. However, even if Arsenal decide to use there academy boys PSV can not do anything and I believed arsenal won't use there full squad because they still have important matches to play and they have already qualified in the champions league.
