Mominul Haque said Bangladesh needed a greater number of fixtures against the top sides in the world in order to progress in Test cricket.
Mominul, who was handed the Test captaincy baton following the shock suspension of Shakib Al Hasan, spoke on the requirement of a paradigm shift in his side's attitude towards the longer format.
Bangladesh were blown away in little over two days in Kolkata by a rampant Virat Kohli-led Indian team, which completed another Test series whitewash on home soil.
The visitors had earlier succumbed to a crushing defeat in the one-off encounter against Test newbies Afghanistan in September.
Mominul felt the problems plaguing the Test unit were prolonged in the absence of regular matches versus quality oppositions.
"Everyone knows that we don't play a lot of Tests... so I think we can overcome these issues," Mominul told reporters with Bangladesh scheduled to play 10 Tests next year as part of the championship.
"There's no room for excuses. Losers give excuses. I am not giving it," he bluntly admitted.
Mominul, 28, claimed his team's fortunes were not shrouded in gloom despite the failure of youngsters to step up to the challenge.
While India's pacers repeatedly ran through the Bangladesh batting across the two games, the likes of Al-Amin Hossain and Abu Jayed were impressive only in patches but Mominul believed fast bowling talent was on the rise in the country.
"I think we will improve. There are more sporting wickets in domestic matches and pace bowlers are coming up."
"So I think we are on the right track."
The touring party was beset by several crises in the lead-up to the series with a players' strike initially threatening to cancel the trip to India.
Later, Shakib was slapped with a two-year ban, with one year suspended, by the ICC for not informing the authorities about corrupt approaches.
Bangladesh also missed the services of veteran opening batsman Tamim Iqbal due to family commitments, though the left-hander had been undergoing a lean run.
"We have been missing them since the start of the series. But we shouldn't use it as an excuse," said Mominul.
"Opportunities opened up for others. It was an opportunity for me as a captain. But we couldn't grab those opportunities."
