The post you replied to was about the "best players". Is it your statement that Martinez, Romero, Mac Allister and Alvarez are among the best players?
France won in 2018 with players like Umtiti, Matuidi, Giroud, Nzonzi or Pavard and I think it's pretty safe to say they aren't the best at anything.
Those might not be the best players, but they did their job pretty damn well at the WC.
And that's fine because Football it's a team game, Argentina itself didn't win shit with the individual quality of Zanetti,Ayala, Riquelme,Cambiasso,Zabaleta, Aimar, Redondo,Saviola,Veron, Tevez, etc
Football is a team game, if you put Messi in a lesser national team like Poland he isn't winning shit.
