nothing, it's just a flawed argument, even though I actually agree with statement itself.
we have Portugal beating France on their own ground without Ronaldo, which for you, is a freak result (and I agree). they you mention your one single game which you've lost without Ronaldo, against Switzerland, as true reflection of your (Portugal NT) quality. but you don't accept all those games in which Argentina struggle without Messi as true reflection of their strength - for you, they are perfectly fine without him, even though results clearly suggests otherwise.
this isn't FIFA or FM. yes, they have Pastore, Aguero and Di Maria, but they obviously do nothing against Paraguay, Brazil, Bolivia etc. who cares how they play against Watford or Nantes when they obviously can't replicate the same form for their NT? football isn't played on paper.
