who will open with Wasim Jaffer in Test matches against Bangladesh?

That just shows that BCCI is in a total experimentation mood right now. If not Sehwag then they should have given any youngster a chance to open but they chose to have a make shift opener rather than a genuine opener. Now it seems in all likelihood it will be Yuvraj singh opening the innings. They've dropped Sehwag as both Ganguly and Yuvraj have been playing a lot better than Sehwag and with number 3,4 and 5 reserved for Dravid, Tendulkar and Laxman respectively only number 6 and another opening position is left so they chose to have Yuvraj as make-shift opener. If they would have chosen Sehwag too in this test team then he would have been picked in playing eleven as a specialist opener and that would have meant that either ganguly or yuvraj would have to be left out of playing eleven, so the selectors decided to drop an out of form Sehwag and give both Ganguly and Yuvraj enough opportunities.
