Rohit Sharma bemoaned India's shortcomings with the bat after they suffered a stunning one-wicket defeat to Bangladesh in the first ODI of the series on Sunday.
Mehidy Hasan was the Tigers' hero, putting on 51 for the last wicket with Mustafizur Rahman to secure a highly unlikely victory at Sher-e-Bangla National Cricket Stadium.
India looked certain to take a 1-0 lead after taking five wickets for only eight runs, putting Bangladesh on the ropes at 136-9 in pursuit of 187 to win.
Mehidy came to the rescue, making an unbeaten 38 with support from Mustafizur (10 not out) to get his side home with four overs to spare, the pair defying the odds by combining for Bangladesh's second-highest 10th-wicket stand.
The tourists had also collapsed, slumping from 152-4 to 186 all out, KL Rahul sparing them huge embarrassment by making 73.
India captain Rohit warned they must learn to handle the pressure after a stunning end to the start of a three-match series.
The opening batter said: "We did not bat well. We bowled pretty well and kept them under pressure until the end. They held their nerves in the back end.
"If you look back at how we bowled, of course the last few overs, we would have liked to get a wicket. We kept taking wickets all through. It wasn't enough runs. Another 30-40 runs would have made a difference.
"With KL and Washy [Washington Sundar, who made 19], we could have got there. Unfortunately, we lost wickets in the middle, and it is not easy to come back. The pitch was a bit challenging, the odd ball was turning.
"You have to understand how to play. There are no excuses, we are used to such types of conditions. We need to look at how to bat against their spinners in these conditions. The genes are there, these guys grew up playing in such conditions.
"It is all about handling pressure. Once you do, it gives you confidence. It is important to learn how to handle those pressure situations. Hopefully, we change things around in the next game."
