Everything needs a process, Luis Enrique cannot make PSG perform well in every match in a short time. Luis Enrique job is not as easy as turning the palm of your hand, it takes effort, time and patience to achieve the desired results. PSG have tried to do something that no other team has ever done or even found difficult, they once had a luxurious squad with a series of stars, but still failed in the UCL. Luis Enrique job is to make PSG capable of winning the UCL trophy and he also needs to maintain his dominance in Ligue 1, Management must give Enrique space and time to bring PSG to success in the UCL.
This is what everyone who talks about PSG repeats, the coach needs to be given more time, maybe it is so at least it worked for Guardiola at City, he came close to this goal many times until one day he did it. PSG by the way also often come very close, but there is always something missing, and when Enrique was in the semi-finals, I will say that it was noticeable that PSG needed to strengthen the attack, even despite the fact that they had Mbappe, although in the last matches he most likely thought about Real more than about matches for PSG, because his performance has noticeably decreased.
You are right their striking force at this time doesn't appear productive enough but they have got a really fair midfield and defense, their attack needs few adjustments too, I was expecting they would use this transfer window to make up for the strikers but it appears they still have some resentments holding them back in making the appropriate moves for the strikers at this time. The most I have seen from PSG has been them linked to one striker or the other and still end up not properly sealing up the deal at this time. Most likely Enrique has got his plans and a strategy that can work anyways.
PSG have strengthened their midfield and defense, but for some reason Enrique is in no hurry to transfer new forwards, perhaps this requires special selectivity in order to buy the best forward, or Enrique has a different vision and perhaps he only counts on the forwards he already has in the team. I would like PSG to have a good forward, especially considering how much the PSG attack line has lost in recent seasons...
