You are right. Judging by their strong performance in their domestic league and also the Champions League this season, I think PSG have a chance of winning it. As for the match against Aston Villa, PSG will definitely be favourite based on their overall performance and squad depth. However Villa's recent form and home advantage could make it a tougher contest than expected.
It could be that Luis Enrique's influence could make PSG end their long wait, after successfully eliminating Liverpool, their motivation will increase 2x more than before, especially since the opponent they will face is weaker than Liverpool.
However, PSG must remain vigilant and must not underestimate their opponents, they must remain focused on their goal because if they succeed in qualifying for the next round, they will face the winner between Arsenal vs Real Madrid, it will be much more difficult because each team will try to show their best performance in order to appear in the final.
Luis Enrique is a great coach and has given a method to the new team and the whole environment is happy, just see the statements that Gigio Donnarumma did when he was talking about renewal of the contract, he specifically said with his prosecutor that the intention is to stay at the PSG and that he is very happy to play with them, so I think he can really go and beat everyone this year this year
