Actually I still have a lot of doubts about how much chance Paris Saint-Germain will have of winning this match, because PSG Football Club was not able to win in the previous match. We watched the previous match which was held at PSG's home ground but the match we are going to enjoy next will be at Liverpool's home ground so I think this match is definitely going to be much more difficult for PSG. Even on that day we have to keep an eye on another important match, even two teams of that match are Bayern Munich and Leverkusen. I believe that this match may be the most attractive.
I partially agree with you that the home advantage might come into play for Liverpool who in my opinion have usually been strong at home and thereby turning it into a fortress where most clubs are usually scared to visit. But on a neutral ground this is a champions league knockout stages, where different things unfold. For me if PSG can be able to handle the pressure of the Anfield crowd and play almost similar football like they did in the first leg by pushing Liverpool home to defend or form a low block again then they might actually stand a chance because this wouldn’t be the first time a team comes to actually steal point from Liverpool on this ground. Real Madrid does occasionally so it is possible.
As for the Bayern Munich vs Bayer Leverkusen game I think this tie seems to be Over for me considering Bayer Leverkusen recent form
