Zhang Jike
Chinese National Team coach Liu Guoliang remarked that Ma had all the tools necessary to be the best, yet at major tournaments, he had so far lacked sufficient mental toughness to play to his full ability when under pressure. This was evident in his losses to Timo Boll and Vladimir Samsonov in the 2008 and 2009 World Cup semi-finals as well as his defeats to Wang Hao (4–1, 4–2, 4–2) in the semi-finals of three consecutive World Championships (2009, 2011, and 2013). Although he performed well on the ITTF World Tour and in domestic competitions, Ma never made it to the final of the World Championships in his first four attempts. This led to many believing he was inferior to compatriot Zhang Jike, who completed his Grand Slam in just over a year.
