I don't think that Sachin most century's record would be broken by Ricky or any other batsman, in this era.
I would like to draw your attention towards the fact that during last 05 years, Sachin has gone out for 02 years almost, due to his serious Elbow injury, even then he made 11 century, and dont forget the pressure which Sachin taking over the years. Also, it's not always easy to make come back after such an serious injury.
I personally wish him all the very best, to make atleast 50 century in both form of the game.
