Angers is not a team that is comparable to Paris Saint Germain in terms of strength, even in appearance they have significant differences. The only thing that can make the Angers win in this match is luck, even a draw is very good for them at this time. Paris Saint Germain are the clear favorites on paper, so they shouldn't be struggling.
The luck factor cannot be denied, but logically I also don't think that their match will end in a draw because the match was played by two very different teams this season, where PSG is at the top of the standings and Angers is the team that might be relegated after this season is over. So it should be easier to predict who will win the match and I think the victory will still belong to PSG.
