Speaking to mediapersons after stroking a confident 60 on his Test debut, the 21-year-old opener, who was flown in as a late replacement of Marcus Trescothick, said if he had been told he would be opening in the first Test here, he would have laughed it off.
He said if it was going to happen, this was the best way to happen, to be pushed straight into the match.
''Once I reached the middle, the adrenalin started flowing,'' he added.
Cook said it felt good in the end to get out there and have a decent knock, especially when he did not know what to expect the least.
The Essex opener also revealed that his main strength was his patience. ''In India you need tons of it to succeed against bowlers of the calibre of Harbhajan Singh,'' Cook said.
Speaking about the Indian bowlers, he said this was the first time he had faced someone like Harbhajan and now he knows why Indian spinners are rated so highly.
''Every delivery would be a different one and you needed to concentrate extremely hard to succeed here against bowlers like Harbhajan and Kumble,'' he opined.
On the captaincy of Andrew Flintoff, Cook said all the boys know about the misfortune, which their team has endured here and, therefore, they are more determined to rally behind Freddie and give a good account of themselves on this tour.
