Of course I don't believe there's a rule that works for all players . It's absurd.
I don't mention things that are basically common sense to me, but rather assume they are common sense for others as well. It's how I operate in real life. If someone gets confused by things that are easily implied and fall into common sense area, it's usually a good sign I need to move on.
No you made out it is 'common sense' for players as young as Pedri not to play so many games.. then not a peep when Gavi at younger age doing same.
Yet completely ignore how reports say Xavi rushed back Pedri from this exact injury earlier this year and he relapsed on it then and injured again on it now.
Or ignore how Araujo now out for weeks afetr playing 90 mins a few days after coming off as felt tightness.
Not a peep about those... clear why.
Yeah, it is prefferable to not overplay very young players. Absolutely. Gavi being an exception doesn't change that. His minutes should have been handled better too, no doubt. As in he should have played less.
Said these things many times. Normally a club like Barca should have players in their prime starting, high class players in their mid 20s and late 20s. And players like Pedri, Gavi joining from the bench.
Yet there was not a peep when Gavi playing so many minutes at a younger age....clear why.
There is no issue with Barca starting players like Pedri and his age.
Pep bought Kovacic who is a discount version of Frenkie and made him a starter.
As said, some players tolerate a high-volume workload better than others. It's the same everywhere. Some workers can carry 200 boxes and don't get very tired, others need a rest after they carry 60 boxes.
The human body tolerances differ from person to person. But as a general rule, very young players aren't prepared to deal with the intensity of the mens game very frequently, as to start every game.
There is no such thing as "mental gymnastics" in real life. These are expressions from silly forum games that don't actually exist.
If I can clear it up for you just ask and I will. Like I did today.
The main arguments are all the same, but I can't exhaust every single mini-argument that the major arguments create because I don't get paid big bucks to comment here. This is wasted time in many respects.
