"It's too many, last ten overs saw them score almost 110 runs which does hurt. It's very tough when you've got people like Dhoni at the end. You get exposed when you don't quite get the skills right," Cook told reporters at the post match press conference.
India relied on a brilliant all-round display to thrash England by an emphatic 127 runs in the second one-dayer here today.
India first posted a competitive 285, riding on captain Mahendra Singh Dhoni's 72 and Ravindra Jadeja's 61, before the bowlers skittled out the visitors for a paltry 158 in just 36 overs to level the five-match series 1-1.
Cook was all praise for Dhoni's big-hitting prowess and said his late-order surge changed the complexion of the match.
"He (Dhoni) is probably the best player in the world in those situations, in these conditions."
Dhoni sent the pace trio of Steven Finn, Jade Dernbach and Chris Woakes to all parts of the park in the closing stages but Cook declined to introduce the occasional spin of Joe Root which the English skipper said wasn't an option.
"You're always going to get a hindsight, but probably one batsman you don't want an offspinner bowling to is Dhoni. We've seen him a number of times and with a spinner at the end, it's very hard to bowl to him. So, look, clearly when you get hit for 68 runs in the last five overs, you think, maybe now, you could have done things differently. But at the time, for me, it was a very big gamble to make," he said.
