"We did not compete at all in the series in Sri Lanka. We have been very competitive here in the first Test that's a huge positive, credit to everyone in the team and the support staff. We got tougher, we got success in UAE and played well here," Pothas said at the post-match media conference.
Sri Lanka were routed at home 0-9 across three formats by India three months ago but they bounced back to win two Tests against Pakistan in UAE.
Pothas said the side which is in transition after the departure of two legends -- Mahela Jayawardene and Kumar Sangakkara -- are up for the challenges.
"Process began in Sri Lanka absolutely. Things like that do not happen overnight. We are certainly not going to be counting our chickens... We played a couple of good Tests against Pakistan, were competitive here but we have a long way to go. This side is going to be a very good side looking into the future there's no doubt."

"It's always a concern when you lose seven wickets. But the more often you play, I think these two series back to back against India will help in making of the Sri Lankan team of the future.
"You become better when you play against a quality team under pressure. It's a concern but I'm more excited about how we fought and came out of it, looking back at all four days."
Despite little to play for after two rain-curtailed days, India and Sri Lanka played hard for a win with words being exchanged frequently on the field.
"We bowled very well, we fielded very well and the intensity was good. We did have India under pressure. Virat played a fantastic innings to set up a very good game of Test match cricket. I don't think anything went wrong. It was a very good cricket from both sides," he concluded.
