Meanwhile, although impressed with England's batting performance, Nasser Hussain was critical of India's fielding on day two.
Cheteshwar Pujara dropped Cook on 17 - a costly error - but throughout the day the India fielders were fumbling, making simple mistakes and allowing England to take quick singles.
"It was diabolical," Hussain said of the hosts' fielding.
"It's a bit of a cultural thing [India's fielding problems]. They love to bat and be Sachin Tendulkar, they love to bowl and be Anil Kumble, but fielding is not part of their psyche.
"It's hot, it's hard work, you field for a long time and you don't get a fielding contract for the IPL - it's all about bashing sixes and fours.
"Batting and bowling is very important, but fielding is crucial and England are going to run them off the field for the next day and a half."
