By saying inexperienced of course I mean the kind of experience with top teams. This was unnecessarily risky for them. PSG only needed a winner manager who had a good system to apply for this team. We will see if Luis Enrique is the right man for the job. Because his strategies are different from the usual for PSG.
I wonder in what sense this is a trio of "dream"? They showed very average results (and the results are the most important thing if we talk about sports and not about brands) and by the way, if you remember, they had very long periods when the three of them played significantly worse than when, for various reasons, one of this trio on field was missing.
When this trio was first built I was looking at it admirably. Because each one of these players was a special player. But things didn't went just as I expected. Neymar was getting injured quite often in the first place. I couldn't see him playing a full season properly. His statistics were still impressive when he played but this doesn't mean anything as long as he misses so many games.
Messi and Mbappe were still doing very well but it wasn't enough to reach their main target of course. By saying a dream trio I meant that they seemed to me like that when Messi was first brought here. The situation after that was exactly as we both mentioned.
