PSG vs Dortmund
PSG is very superior in terms of players compared to Dortmund, PSG plays at home. Looking at Dortmund's previous matches, they always conceded. Their defense has not been good this season.

PSG have had a tough start to the new season and I am not at all confident in PSG right now. The club had a tough time in the Champions League and in previous seasons. Now the Parisians don't have such a strong team. Maybe the French club will still surprise everyone and they will show a good result in the Champions League. But the situation in the French championship so far says otherwise.
Borussia Dortmund is a very difficult opponent. I do not think that they will lose in this match, even despite the status of guests.
However it is not yet clear who will win the match because it is still early days and of course both teams this season have similar weaknesses including PSG only relying on Mbappe to win and Dortmund have lost several of their mainstay players too.
If have the desire to bet on this match I prefer to take a draw or score between the two teams to minimize losses and in addition it is very difficult to predict who will win.
