Australian great Ricky Ponting is concerned about top-order batter Steve Smith`s indifferent form as the team gears up for the gruelling Border-Gavaskar series in India early next year, and believes that while the cricketer`s technically look sound, opposition teams may have found a way to stop him.

Smith`s form is vital as Australia aim to secure the World Test Championship (WTC) final berth and the series against India will play a huge role in deciding the team`s qualification for the second edition of the WTC final.
