IMO, Messi always took responsibility when he was with PSG last season. even though if we talk honestly, even based on statistics, Messi is the most consistent player of all existing players. The problem is, PSG management is always in control of their team's bag. in fact, my guess is that Galtier was not given the opportunity to bring in the players he wanted. Let's remember again, if I'm not mistaken PSG didn't bring in a single player in the January window last season. "correct me if I'm wrong" even though in reality, this team really needs a creative attacking midfielder.
Maybe that's why Galtier tends to change his patterns and systems. Plus, the sports media always report that in the PSG dressing room there is always conflict between the players. One more thing, the club's mistake for me is that they didn't use the services of a coach with the required experience who could handle a team as big as PSG and control the dressing room. thus, it can reduce conflict between the players.
Now, PSG has appointed a coach who has experience requirements. even so, it doesn't guarantee that this team will win trophies in various competitions. but at least, PSG can still maintain the Ligue 1 title. Even though currently, they are in 3rd place. But gradually, PSG will return to the top of the Ligue 1 standings. Currently, Enriqeu is building his team to have a strong foundation. Plus, some of the new players they have brought in will eventually reach their best level of play. Champions League, not this season. maybe, next season. but at least, PSG has a chance of qualifying for the next round.
I have to say that you're correct when it comes to the consistency of Lionel Messi, Slightly from Neymar Junior and that of Kylian Mbappe because he was scoring important goals for PSG! The management are not really in control of what the manager has to do.
You see the manager Galtier Christophe, have you checked how well he did with his last club in League 1 Competition?! Man ain't no big and top notch coach, he should be in the same class of Steven Gerrard and Frank Lampard.
Such Coaches without experience of a big club should never be given the chance to handle Paris Saint Germany never again! The journey to the top of the league is still long and Paris Saint Germany can still do that.
