Following their recent demolition of England in all formats, Virat Kohli's India will be heavy favourites to cement their status as the world's number one Test side in the one-off match in Hyderabad when it begins on Thursday.
But wicket-keeper Wriddhiman Saha warned it was vital not to be distracted by the prospect of a looming high-profile series against Australia later this month as they face the ninth-ranked Bangladeshis.
"Ranking-wise one may think they will be easier opponents on paper but we cannot underestimate them," said Saha.
"I don't know when are the Aussies coming but as of now the focus is on Bangladesh Test. After they're here we will think about it."
Kohli's men are looking to set a new milestone after equalling India's record of five consecutive Test series triumphs against England, New Zealand, West Indies, South Africa and Sri Lanka in the past 18 months.
Bangladesh held India to a draw in June 2015 in a rain-affected Test in Fatullah the last time they met.
They have lost six of eight home Tests against India with two drawn but now get a chance to face them away from home for the first time since gaining full status 17 years ago.
Bangladesh's Test win in the drawn two-match series against England last October has given the team belief that they can compete against the top Test nations
