New Delhi: Replacing the Indian skipper in a Test match is not an easy but former wicketkeepers feel that Wriddhiman Saha`s calm demeanour could be an advantage when he dons the big gloves during the final Test against Australia in Adelaide, starting on January 24.

"I believe this is a make-or-break chance for Wriddhiman Saha. Replacing someone like Mahendra Singh Dhoni, though for a match, is not an easy job. But if he can manage a decent performance like—keep well and bat for about two and half hours and score a 50, his place as second `keeper will be sealed," former India stumper and chairman of selectors Kiran More said.

For More, it`s Wriddhiman`s good work with the gloves that makes him more of a `keeper-batsman and if Dhoni retires from Tests after 2013, he would be an ideal choice in longer version.

"Wriddhiman is a technically correct `keeper. But Test cricket is a different ball game. He has been on a number of Test tours and must have adjusted to dressing room environment by now. A good show in Adelaide will mean that India will have an ideal replacement, if Dhoni calls time on Test cricket in 2013," More added.
