In China, Korea is considered the pinnacle of 'cool'. If something is trending in Korea, China (and lots of Asian countries) will lap it up. I've no doubt that Lage is under pressure to keep Hwang involved to the detriment of others. Hwang's SM output often completely contradicts the result or performance (team or individual) of the match that has just taken place - it's all about engagement of the international fan who probably didn't even watch the game that just happened.
It's all very unsettling - that Shi interview was bitterly disappointing for anyone whose sole interest in the Wolves is the performance of the team on the pitch. It's as if that has become an after-thought. The only thing I can cling to is that the global "brand" must, surely, rely on the first team staying in the PL. It seems as though we'll be mid-table at best for the foreseeable - it's what informed the appointment of this manager and the attitude to recruitment since the Silva/Semedo window (when I can only assume the strategy was different).
