5 factors that might have influenced AB de Villiers’ shocking retirement 

#3 His own fitness concerns

ABD took a year-long break from cricket from 2016-17

AB de Villiers’ own fitness and mental health have not been at the very best. He took a year-long hiatus from cricket from 2016 to mid-2017, saying he needed a break from the game.

Keeping this in mind, it can be assumed that his mind and heart were not at the right place. In his retirement video, the legend himself said that he feels he has run out of fuel in his tank and is now tired.
