The problem isn't Son Heung-min; it's the riders underneath him

If Son Heung-min were the problem, he would have been a problem at Tottenham too. He never had these kinds of issues while playing for overseas teams. He got along well with foreign players
And he had no issues with his seniors or peers either. I haven't just watched Son for a year or two. With many of the '92 line' players retiring and the '96 line' due to take over, it seems like a power struggle is occurring because a star player like Son Heung-min is still here.
