Li Wei doesn't like Watson.
It has nothing to do with their long-standing grudges, as Li Wei never paid attention to those so-called "grudges"; he simply doesn't like Watson's attitude towards the game.
When the game is going well, it's Watson's credit; when the game faces setbacks, it's his teammates' responsibility.
In the face of adversity and thorns, Watson's attitude is typical of an arrogant and self-centered prodigy, unwilling and unable to bear the responsibilities of a leader.
Perhaps they have talent, each one a genius; but they will never grow into truly outstanding players, ultimately becoming an unremarkable figure in the professional arena, even less valuable than blue-collar players.
Clearly, that's a problem.
