All the teams in UCL are the big teams from varied top leagues. All the teams must be serious since the early stage of UCL competition. Moreover, when it is already in quarter-final, only the stronger teams can reach this round. Aston Villa is strong team, they come from EPL that is the most competitive league in the world. It is totally a big mistake if PSG underestimates Aston Villa. There is no guarantee that PSG can easily beat Aston Villa although they can beat Liverpool. PSG must be very careful because Aston Villa is much stronger recently, they have a better squad recently. And they are in their best form as well.
Yes, of course the teams that can enter the Champions League are selected teams that have extraordinary performance. Moreover, the teams that have made it to the knockout stages like now, there is no doubt that these teams have very great performance. Then talking about the Aston Villa VS PSG match, I personally do not have a prediction at this time regarding this match. But if we look at the previous matches of these two teams, it can be concluded that this match will be very tight, and it is possible that this match will end in a penalty shootout. Because as we know Aston Villa and PSG are indeed strong teams in their respective leagues. Although in reality PSG is superior in its league, because it is at the top of the standings in Ligue 1. While Aston Villa is only in 9th position in the English league. But even so, in the UCL sometimes the ranking in the league is not a strong guarantee to win. Therefore I think this match is still full of mystery and difficult to predict.
