In a way, him crying openly shows his humility and regret.
He let his nation down and couldn't live with that. He knows the world will make fun of him crying.
After scoring his pen in the shootout, he apologizes to the Portugal fans for today instead of celebrating. Now, that is humility.
People might call him arrogant and rightly so but atleast he has the integrity and humility to immediately admit his fault instead of playing victim. He'll be the first one to blame himself for this game.
Respect.
