What Ronaldo is mistaken about is that the Portuguese players are actually quite nice

If it were a national team filled with tattooed thugs, aggressive personalities, and club-level bad attitudes with anger management issues—like the Argentina national team—he would have been ostracized in the locker room and ignored long ago.
Seeing how the Portuguese players at least show him outward respect proves they are quite mild-mannered. That is why it makes no sense to demand they treat him the way the Argentinians treat Messi.
