He dint said that he wont retire on next series. He just said he is in no hurry to think abt it. When team India took on Aussies last time in tests, India crushed them. But in the first test it was he who fought for India and led the way for India, even though after that he failed to make it big. Even now in moving bouncy tracks we need some one like Dravid, Sachin, Lakshman. I am not saying he shud not retire. I am just saying respect him. Let him decide. I dont think he wont retire if he performs badly again. Let us give him a last chance for the joy he had given our country over the past two decades.
You need to create another record by being the only player to have played with his son for India. And the press will be gushing about this record. Do not retire. We all want you to play with your son and daughter for the Indian men's cricket team.
Dhoni clearly mentioned in the recent interview that he wants players who not liability to the team. This hint is enough for all. Now if you still do not get from this, than wait for Dhoni's supercool attitude he played with Dravid and Laxuman.
