Yep. After seeing how PSG beat Liverpool then I think the majority of us will all think the same as you. Including I personally agree with you. because Aston Villa and Liverpool even have quite a big difference in strength in the Premier League. So it seems quite logical that PSG, who managed to beat Liverpool, will most likely also succeed in beating Aston Villa. I don't mean to underestimate Aston Villa, but from the data it can be understood that way.
Personally, I would also prefer to favor PSG in the quarter-final match. And it is very likely that PSG will indeed be able to qualify for the semi-finals. And if they are lucky, PSG could even go further, namely to the final this season. Remember Liverpool was initially the strongest candidate this season in the UCL. but PSG made Liverpool's game chaotic in the round of 16 yesterday. We even seem to see Liverpool as not being Liverpool. Maybe that's because PSG was able to handle Liverpool's game well.
It’s understandable that after PSG beat Liverpool they are even stronger than before, their performance have increased in all competition. However, PSG against Aston villa it’s kind of unpredictable game to me, because I can’t guarantee that PSG will win the match. because PSG also won against Liverpool doesn’t guarantee that they will beat Aston villa, some time luck follows we all know that Liverpool is stronger than PSG.
But after all we all gave Liverpool direct winning in that match but at the end what happen? PSG won the match. So we shouldn’t give PSG high chance of winning at this moment even though Aston villa are not strong as Liverpool everything can still happen.
