"In that dressing room, knowing what we had achieved, it was a special place and will live long in my memory."
England's success was all the more impressive given their terrible start to the series. A
in the opening Test led to gloomy forecasts of a 4-0 series whitewash.
"Of course there was doubt," said Cook, 27, who was named man of the series after scoring three hundreds and 562 runs in the four-match series. "There is always doubt, especially halfway through day two [of the first Test] when we were getting rolled.
"I was surprised at the level we managed to achieve so soon after Ahmedabad. I was talking [there] about playing to our potential, but I was surprised we managed to do it straight away and put all those doubts to bed and prove it to ourselves."
He added: "We didn't handle the Ahmedabad wicket well but the others were all very different and we adapted well. The bowlers have been brilliant and our batters have contributed big runs.

"There were handshakes, hugs, embraces and slaps on the back all around in the England dressing room. They have worked so hard in this series. What odds were there on us witnessing that? It's quite remarkable. They have done it the hard way, through outstanding leadership on and off the pitch."
"Everyone in the squad can be very proud, especially after Ahmedabad and that heavy defeat. The guys who played a couple of games all made a difference and the amount of effort the guys have put in for me, I can't ask any more.
