A player should retire when people ask him WHY are you? not then when people say WHY NOT?, still after having a disappointed tour of Australia, still Sachin has a support. So, i think it's the right time. Well, the right time was right after winning WC. Now his age is getting older and older. VVS Laxman has also the same problem, he should have retired earlier but because of not, he is always been criticized on daily basis. Sachin's 100th century is creating pressure not only on him but on the rest of the team as well.
