"It has been a tough couple of weeks before this tour, but the players deserve a lot of credit," Domingo said.
"The energy and desire they have shown in the last ten days has been fantastic. They were willing to try new things. They are playing against a quality side away from home. If someone said to us two weeks ago that we will be one-all coming into Nagpur, no one would have believed it.
"So we are pretty happy where are, and it is a great opportunity tomorrow. The guys are really excited by it. At the end of the day, India are one of the best sides in the world. No one gave Bangladesh a chance, but we think if we play to our potential, we have a chance tomorrow."
Domingo also pointed out that they want to be known as a more settled team.
"We feel India has a lot of left-handed batters in their top six," he said. "Our offspinners worked a game ago, but just because it didn't work in the last game doesn't mean everything has to change. We don't want to be a team that makes knee-jerk reactions to a loss. It has been the case for this team for too long. We want to back a certain group of players.
"If somebody has a bad game doesn't mean he doesn't play for the next six months. It is part of T20 cricket. We believe that those who played in the first couple of games are good enough. We don't want to make a lot of tactical changes just because someone played really well against us."
But Domingo also added that the team will require at-least one Bangladeshi batsman to score some big runs in order to beat India in the decider in Nagpur.
"Mushfiqur [Rahim] got the big score in the first game, so we won. Rohit [Sharma] got the big score so they won the second game. When we get to the thirties, we need someone to get into seventies or eighties.
"[Bangladesh's batsmen] are not trying to get out. They are just making bad decisions in crucial stages of the innings. I don't think it is a technical thing. It might be decision-making at crucial stages that they need to improve."
