I have heard that both Sachin and Sehwag have not been picked for Asia Cup.......
So who will open with Gautam? There are a couple of youngsters - Rahane is my best bet.
Would like to see Rohit Sharma, Pujara and Tiwary getting a good exposure
Shewag is the ODI/T20 V/C so it's highly unlikely they would force Tendulkar out and drop Shewag.
It's common knowledge that Shewag was rushed back from a major shoulder reconstruction, and at his age, recovery takes along time. It must also be pointed out that India wins more when he plays.
From what I've seen on cricinfo, Rahane's form has fallen away since he returned from Australia.
I think Shewag and Gambhir will open. But Gambhir should've been the one dropped. Shewag and Rahane would be a good opening pair. Followed by Kohli, Rohit, Dhoni, Raina
