Neymar had all the requirements to become one of the greatest players in the world. However, despite his creative playmaking and skill with the ball, he was also undisciplined, irresponsible, disorganized, and a "diver" (a term used for a player who feigns injury). Due to his indiscipline, he was constantly injured and only thought about making a fortune, whereas we know that most players seek fame and professional respect. Personally, I wouldn't call him up.
