Former South Africa captain AB de Villiers cited fatigue as a major factor in his decision to bring an immediate end to a stellar international career. De Villiers insists his choice was not motivated by a desire to spend the rest of his career on the lucrative domestic T20 circuit but because competing at the top level had left him weary. In a video on his Twitter account, he said: "I have decided to retire from all international cricket with immediate effect. It is time for others to take over. I have had my turn, and to be honest, I am tired.
