Actually, when viewed from the whole, PSG is now like an avenger when it is aligned with players from every club in league 1 because from every line there are players who are above average which makes this team very strong.
and it is certain that when clubs in league 1 will make defensive strategies to play against PSG so that they hope not to concede, because winning matches is very difficult, especially for teams at the bottom of the table.
at least a draw is the most likely choice for them.
but it's only in league 1 because speaking for the Champions League I think it will be a little different because the Champions level is higher and indeed PSG are strong but for the Champions level they are still on a par with other teams such as City, Madrid Chelsea and some another team.
Indeed, PSG now seems difficult to beat but if I look at the previous match where PSG was still unable to win big with a clean sheet, then it means that PSG's defense is also not as perfect as imagined. We're just hypnotized by having Messi there and I don't think it's promising for PSG to go further in the UCL. I personally will still be looking forward to how far PSG will go in UCL, because as we know in UCL there will always be surprises, especially from teams that are not considered or dark horse teams.
this is a task that the coach must immediately think of a solution for and if seen from PSG's performance it is already good but as good as a team is there must be a weak point that must be resolved immediately, besides that for now PSG's back line is still often missed, especially in attack back, but I'm still waiting for the debut of the two new players in their back line, Ramos and Donaruma because until now this hasn't happened yet.
maybe by playing Ramos at the back, at least we can lift both mentally and in performance because we know that Ramos was a pretty reliable defender when he was at Real Madrid.
and for the champions league I completely agree with what you said because every year there are always surprises, for example, like the 2019/2020 season where dark horse teams like Atalanta and Lyon can even get to the quarter-finals and semi-finals and are able to beat big teams including PSG at that time.
because again, this is football anything can happen on the pitch. no matter the team is strong in terms of money and players, still when 90 minutes of the match goes on, the team of 11 people can survive.
