It's not the first time I hear it but it's dumb and false. Dumb because it has become a talking point among pundits who don't actually think much and people just parrot it, I mean you put Neymar in that list when Neymar is defensively on par with Mané or Salah who as far as I know have never been said to be carried by the team and described as an issue for Klopp.

The fact that we are in a thread about Pochettino and that people are contesting the general trend at PSG by ignoring more than 90% of their games which have been played with only two(Neymar and Mbappé) of these three players and that one of these two players doesn't actually fit the narrative is definitely baffling. I could actually understand the idea that Mbappé plus Messi needs a particular setup to compensate for their poor defensive work but that's beside the point because PSG issues aren't defensive or without the ball but specifically in transition from defense to the attack, their issue is that since 2019 they have gradually created less chances and less shots.
And then you have to wonder this, why would PSG or any club want a manager that cannot organize his team properly unless he has the perfect starting eleven? It means that this manager can't effectively affect your team performances, he adds nothing outside of putting names on a teamsheet. Why is he earning dozens of millions? So yes it's baffling because the fans and pundits that you are using as a point of reference are essentially telling you that the manager is useless and that we shouldn't expect a thing from him while not even knowing the context of the team they are talking about.
Now I want to go back to Liverpool because I believe that they play well as a team and people generally use Klopp as a reference when they try to have a pop at a player, "player x wouldn't start for Klopp". So as I shared above their attackers are not more defensively involved than a prima donna like Neymar, so I will jokingly claim that that's two players that Liverpool have to carry, now has anyone looked at Robertson and Alexander Arnold defensive contributions? They are not actually that productive either, so are Liverpool carrying multiple players defensively? Why no one use the same talking points when talking about Liverpool, what is the difference? Because all of Hakimi, Nuno Mendes, Bernat, Abdou Diallo have done more or as much as Liverpool starting fullbacks from a defensive standpoint. So something is amiss.
Here is the thing that pundits and fans seem to forget, every team is different because every team has different players that have different strength and weaknesses, every team has to compensate for weaknesses and accentuate strengths of their players. No team is made of perfectly balanced players, they all have to take into account that some players will need more help defensively and others will need more help offensively, that's the norm
