India outplayed the Sri Lankans in bilateral rubbers in recent times.
"If you go by the rankings, India is the top team in the tournament, so they always start ahead of the other teams," Hathurusingha said on the eve of the tournament.
He added, "Whoever plays for India, it is still a very strong team. We have to start well because we haven't been doing well at home. With Bangladesh, because of the last series, we probably have a little edge over them mentally."
India and hosts Sri Lanka kick off the tournament here tomorrow.
Although Sri Lanka have recently showed improvement in Bangladesh, their record against India is woeful. India have won the seven most-recent T20s between these sides, and are ranked third in the world, while Sri Lanka are eighth.

India also rested several other limited-overs regulars in fast bowlers Bhuvneshwar and Jasprit Bumrah, wrist spinner Kuldeep Yadav and all-rounder Hardik Pandya.
