No no nothing wrong with my mind, nwy5633. Oh, by the way, I am Indonesian.
Rexy is Indonesian and an Indonesian National Badminton hero. He is very capable. Thus, as a professional coach now, he is helping Malaysia a lot. By helping Malaysia win, that means he will also make Indonesia loose... It does not feel good when your National hero is helping another country that can actually beat you...
Imagine Lee Chong Wei coaching the Indonesian singles team very very hard to beat Malaysia. His success means Malaysia's defeat. As a Malaysian badminton fan, is that a good feeling?!? Wouldn't you prefer Lee Chong Wei just coach Bulgaria or Canada or something with high pay. He makes money, yet do not actually have to destroy Malaysia to be considered performing well.
Thus, I was hoping Rexy would not only threaten to quit, but actually quit from Malaysia. Help some other countries that need its badminton strength to grow, but will not actually can beat Indonesia yet...
