This is what experts are saying:
"The fate of the series leans heavily on the outcome tomorrow. In India a good start to a series tends not to be overhauled. Barring the miracle of 2000-01 - when Laxman and Harbhajan turned Australia's plentiful bread and fish back into a crust and a sardine - no side has won the first Test and lost the series in India since the hosts against Gower's 1984-85 side. On the other hand, since then, only one series that began with a draw has ever gone against India. Tomorrow should be quite a day.
It all looks quite grim now for the ragged Indians. Victory is no longer a possibility. The encroaching rough from all sides has reduced the unblemished original to an oval spotlight in the centre of the strip. The top has come off only on the odd ball, as Monty Panesar has shown, but persistent bowling is not easy to counter, again, as Monty Panesar has shown. Hoggard, Flintoff and Harmison are not bad too. They will need far more application than was shown, for example, in their last Test at Karachi else England will take them to the cleaners. And no discounts too."
In simple words India has to save the match!
