When Chung started tennis, his coach taught him proper ways to hit the ball and serve. And somewhere down the line Chung developed a had habit. Any decent coach would've fixed it immediately. The fact that his coach did not correct his serve motion is disgrace.
If I was his parent, I would ask for refund.
Seriously, Chung's serve is so bad that any decent coach would have forced Chung to change his serve motion.
Probably you don’t know anything about Chung.
When Chung started Tennis, his father was the coach so they can not ask for the refund hahahaha
Even though chung started ATP tour in 2014, first two years were almost part time player and lack of experiences and support were big factors since H.T Lee was only Person who played competitive ATP level tennis in Korea. Chung even missed deadline for FO but fortunately got Wildcard.
Finally he started more ATP matches in 2017 but his playing strategy/game plan were not enough for ATP level.
During winter time, he met Neville then Chung’s game was improved instantly and started win matches. It took less than 8 weeks under Neville. Now more and more people is watching Chung without knowing him and there are too much high expectation from those. I totally agree that his serve has to be changed but not sure Neville can do or not.
His serve motions were changed a little but it’s not working so far. Chung needs serve specialists and hope his manager and his team address this issue now but it won’t be easy.
