May Be it's destiny.. I had a gut feeling, watching him bat in the match against Pakistan the other day, the retirement question was weighing him down. It would be a culmination of so many things for him, when he achieves that 100th hundred and lifting the cup on his home ground!! What other fairy tale ending can a cricketer ask for??
For a sportsman of his caliber and popularity, calling it off a day (atleast for ODIs) on the top of your form, playing the highest challenge in your own home ground. It cant get any better for Sachin !!
