Since March 2015, Cha has been coached by Brian Osher of Canada. Just having Osher as a coach indicates Cha has the potential to become a top skater. Osher coached Kim Yuna, gold medalist at the 2010 Vancouver Olympics, and has been coaching Hanyu Yuzuru of Japan, gold medalist at the 2014 Sochi Winter Olympics, since 2012. In addition, Osher also coaches Javier Fernandez of Spain, Yuzuru’s rival and two time World Championships champion in 2015 and 2016. “Cha has the ability to make any styles his own,” Osher said. “Just as Kim Yuna was Korea’s diamond, Cha can also become that special diamond.” Once Cha turns 16 in October, he will be making his senior debut in the 2017-18 season, the year the PyeongChang Olympics will be held. In less than a year, Cha will have to compete against top skaters like Yuzuru, Fernandez and Nathan Chan of the United States. In the junior division, Cha’s competitions are Dmitri Aliev, 18, and Alexander Samrin of Russia, 19, as there are no other dominant skaters in the age group. “In men’s figure skating, their performance gets better as they grow and get stronger,” Bang Sang-ah, a figure skating analyst with SBS, said. “And this is why there is a big gap in skills from junior to senior events and in age difference. But Cha still manages to compete against skaters that are older than him.” 

The world’s top skaters perform more than two types of quadruple jumps and have about five to seven of them from short and free skating programs. Since juniors cannot have quadruple jumps in the short program, Cha only had two in his free skating program at the World Championships last week. Although he successfully executed a quadruple salco and toe loop jump, he fell executing his second quadruple salco. “It’s better to increase the number of quadruple jumps by one per year,” Bang said. “It may be overwhelming if they try to put two at once. If Cha slowly adds in more quadruple jumps and improves on other skills in his performance, he will be one of the top skaters at the 2022 Beijing Winter Olympics.”
