In the Champions League, no opponent should be underestimated by any team, especially when it has entered the knockout stages such as in the quarter-finals. This means that every opponent must be seen more seriously by any team if the team wants to be in the next round and win with enough aggregate goals to be able to qualify for the other round. Aston Villa is a fairly serious opponent and I think PSG also sees Aston Villa as a dangerous opponent because in the Champions League all abilities will always be deployed by any team without any fear, especially if the team no longer has a chance to become champions in its own domestic league.
PSG is strong team in French League and is close to winning record 13th French title, right now PSG is number one team on points table of french league. Villa is an average team in EPL with 12 wins this season and is at number 9th position on EPL points table. Odds must be in favour of PSG for there upcoming quarter final with Villa but still they must take the quarter final seriously. In football anything can happen, we have seen many instances where mediocre team was able to beat top teams of a League.
don't forget that Aston Villa was the better team in the Champions League compared to the result that PSG had and when we talk about the potential outcome of games at this phase of the tournament, it is not about who is doing better in their domestic league, things can just happen and Aston villa surprises us by knocking PSG out at this phase of the game. from the win probability and seeing that PSG where able to beat the premier league defending champions before they got to this point, all variables suggest that Aston Villa is going home from this point, which can serve as a source of inspiration that can further push Aston villa to play better even though they will be seen as an underdog. it is going to be tough to defend against Dembele who has shown how determined he wants to get the work done against whatever opposition that comes their way, but nothing can be completely written off as long as football is concerned.
