Somewhere down the lane, a licky boom boom down
Add to that the massive pollution there and being so far away from friends, having to uproot your family into a culture shock. Is it worth it when you can get a much higher standard of living in a better place and still be paid handsomely?As @Cal? said there's a high risk with China of not getting paid, be prevented from playing football if there's a conflict and even have to repay huge sums if you put a foot wrong at some point. They also probably aren't paid when injured.
There are numerous examples in China, Russia and middle east of players being shafted. Those contracts look good on paper but are nowhere near as safe as in Western Europe.
Which big pro has stayed there for long anyways? Must be pretty bad there when most of them don't even make a whole year there.
