A score like 4-1 is indeed too much for PSG. Maybe they aren't consistent but they should have been able to get a decent result at least. Newcastle treated them like they were a small team. I'm curious about what Luis Enrique is thinking about this embarrassing loss now. I wonder the same for Mbappe as well.
Clearly PSG won't be successful in the Champions League this season as well. They have too many things to fix. This could lead to Mbappe's making his decision on his future easier. I assume he would rather join a more successful team from now on.
