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.
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 you are right Aston villa shouldn't be underestimated but when we are talk about the quarter finals which do you think has the higher chance of winning? Psg's current form is absolutely on point and I don't Aston villa can beat them. If they could beat Liverpool on their home ground what do you think the outcome is going to be between this two teams. They might probably be in a better form this season but they can't survive for long In the UCL but let's see what happens I might be wrong.
