Yes, it is a little difficult to predict and determine which club will be superior in group F, whereas this group contains top clubs that compete competitively and it looks like the competition is very tight, even though PSG will be superior, AC Milan cannot be underestimated because The strength of the defensive line very strong and on one side Newcastle has an almost perfect attacker but is a little inconsistent in its defense and Dortmund has the worst performance among the other clubs in group F.
If I was just speculating, I would predict that PSG and AC Milan would lead Group F, so I have a chance for these two clubs to be superior in every bet I place.
I think it's really difficult to predict, sometimes we are fooled by the performance shown in our respective domestic leagues. So far PSG and AC Milan are the favorites in Group F, but things could change if key players are absent from each club. I think the second match in the group phase will be very decisive, where the standings will start to form with the points scored. Looks like there will be a surprise in the next match, it will be interesting for later.
However, Group F deserves to be called the hell group, because both PSG, Milan, Dortmund and Newcastle have the same big chance of moving to the next stage.
