With the remaining star player Mbappe, I think the attacking aspect will be much more effective, the inclusion of Asensio and Dembele will play a role in supplying the ball, of course this will make it easier for Enrique to apply strategy. At least if PSG can overcome the intense competition in Group F then the potential that follows will give them more motivation. Of course there is a price to be paid by fighting harder in the beginning. The Champions League journey will not be easy for them to achieve.
Only Mbappe is not enough to make a strong team and PSG need more than him to have a strong attacking system and a strong team need more player resources. Asensio and Dembele came as replacements for Messi and Neymar but those players won't contribute too much for PSG proactive defense at their frontline. It is not important in matches with weak opponents but is very important when facing against biggest opponents in Europe. Losing a ball and don't chase opponent players to stop their counter attacking at the frontline, it will cause nightmare for PSG defenders and goalkeepers.
We agree that the 3 clubs AC Milan, Dortmund and Newcastle cannot be underestimated, therefore coach Enrique's demands are very high and as much as possible he does not underestimate the opponents he faces, especially AC Milan and Dortmund, even without Bellingham Dortmund can still give him quite a dangerous game.
With all four clubs in this group, PSG must solve each match especially first matches very well if they don't want to stop this season too early after a group stage.
All three clubs are able to get points or even beat PSG in group matches.
