Don't make the mistake of using the French League to judge what could happen in the UCL, PSG is a "local champion" that is always impressive in the local league but could struggle externally. And judging by the UCL table, you should easily know that PSG is not a match against Liverpool unless the unforeseen happens. Well, this match is still far, we have 10 days to play the first leg and I see Liverpool winning both legs.
What you said is right but you know how football works, things can happen below your expectations, and only if that happens PSG will have upper hand over Manchester City, but based on performance this season and their Champions League experience, I think Liverpool should be superior, but Slot might have less Champions League than Luiz Enrique which can help PSG little but we yet not certain because we have seen how PSG is performing in the Champions League .
My top favorites for this season’s Champions League is Arsenal because I am confident that Arsenal will win Real Madrid if all players are fit, and if you check the fixtures, only Madrid will be Arsenal’s biggest problem in that fixtures, and once Arsenal is able to defeat Madrid, they can win the Champions League this season.
