I don't think he is going to retire any time soon . He should not .The rot is much deeper and it starts at the top . Dhoni has completely failed as Test skipper . It is not as if good player's are not available , it is just that they are not chosen .
Sachin is not part of Indian T-20 squad . After 2007 WC win, what has been India's performance in T-20 ? What is the reason for India's consistent failure. India's winning percentage against Aus,Eng,Pak,NZ,SL,WI is less than 50%. They get enough T-20 practice in IPL , Dhoni gets the team he wants , yet in last three editions of T-20 WC India has failed completely .
About Sachin - He just cannot stop playing ODI's . He should be playing both ODI's and Tests . It is a ridiculous approach . If he really thinks that he can just come in and start scoring runs in tests then he is not thinking right . He dug himself into a big hole when he stopped playing ODI's . Playing your natural game is not an experiment you perform in one innings and stop it immediately on failure . After first innings he went into an overly defensive mode(I am taking nothing away from English bowlers , they were good) and persisted with it throughout the series . Ridiculous . He should get some lonnng innings under his belt where he will score some runs fluently, possibly in Ranji or in ODI's, preferably ODI's .
Dhoni should be replaced as skipper for tests . Things will sort themselves out. This is not a bad team . It is an OK team . It can be a much better team .
When you have batters like Sharma(for tests, not ODI) , Tiwari , Rahane sitting on sidelines and players like Raina and Murali playing 17 and 10 tests ahead of them you know that something is wrong . Decision to include Yuvi ahead of Rahane was amusing . Who do you include in the test team - a 24 year old fit guy in good form who is consistently scoring runs or a 31 year old cancer defeating hero who has played 40 test matches and is yet to make his mark in test cricket ? Even Tiwary would have been OK .
A bunch of players will have to be removed from the vicinity of Indian team, asked to perform consistently over atleast half Ranji season before Sachin's retirement can be mentioned . If he decides to call it a day , then fine but I hope he doesn't.
And where is the coach of Indian team ? What is he doing ?
