It is a real jolt for the cricketing world as one of the most entertaining batsman and fielder and this will be huge loss for the SA as to find some one like him is really the toughest task. Also before the World cup it has happened to SA will be really shaken with it.
The cricketing world is just shocked to hear this news, he is always in prime form and i consider him as the best player in all the formats and it is really premature to retire all of a sudden, he should have waited till the next world cup to make a decision on his career, i really wish he would reconsider his decisions as he is still at his peak form.
