Hyderabad: Describing Virender Sehwag as key player for India, Australia captain Ricky Ponting today said the Indian opener will be the biggest hurdle to his team's chances in the upcoming Test series against the hosts.
''Sehwag is a key player and he is dangerous once he gets in. He could single-handedly change the course of a match,'' Ponting said.
''Everytime he gets in, he gets a big score and it will be important to contain him,'' he added.
Sehwag has an outstanding record against the world champions.
In 11 Test matches against the Australians he has scored 1132 runs at an average of 53.90, which includes three hundreds and four fifties.
Australia will play four Test against India for the Border-Gavaskar trophy with the first Test starting from October 9 in Banglore.
