Part of the reason the '96 line' is acting like that is because Son Heung-min isn't performing for the national team

People say Ronaldo should retire from the national team because he's getting older and can't perform well anymore.
Even though Son Heung-min is performing worse than Ronaldo, he gets unlimited protection while playing,
so there is some truth to the idea that the '96 line' is stepping up to take the lead on this.
Honestly, if Son Heung-min had performed well for the national team, people wouldn't be saying he should step down as captain.
The professional world is a place where you compete based on skill,
but in his later years, Son Heung-min is just coasting on his reputation.
