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.
The quality of Aston Villa and Liverpool is very different in the domestic league. But I think in the Champions League it will be different. Because there is a very different motivation here too. PSG, which had struggled since the early stages of the UCL, turned out to be able to beat Liverpool very well. And the opposite could happen, namely Aston Villa, who are not favorites, could be the ones who succeed in stopping PSG. This is the Champions League where all the teams that have made it to this stage have their own advantages. Remember last season Dortmund also managed to get to the final by beating many strong teams along the way to the final. And at that time Dortmund were not favorites at all. But I have to be honest, I would also prefer PSG because statistically PSG is still the favorite in many ways.
