"India deserve a lot of credit," said Michael Clarke. "They outplayed us in every facet of the game."
Clarke said they need to work hard and vowed to bounce back.
"There is no doubt we have a lot of work to do. In all facets of the game. There will certainly be no stone left unturned," he said.
He slammed the batsmen for lacking application.
"There is no excuse for that. There will be no break between the Test matches. There will be a lot of hard work, I can assure you," he added.
Indian skipper MS Dhoni said the start given by Bhuvneshwar Kumar on the first day was one of the key factors.
"It was important to get off to a good start. Bhuvneshwar provided that. You don't see fast bowlers getting too many in these conditions," he said.
He reiterated the importance of big partnerships after Murali Vijay and Cheteshwar Pujara laid the foundation for victory with an Indian record second wicket stand of 370.
"We often talk about long partnerships. If you get 40-50, you have to score big. That's what Pujara and Vijay did. That resulted in a massive partnership, which gave us the freedom to accelerate yesterday," he said.
Dhoni was once again modest after winning most matches as India's Test captain.
"Credit goes to the team and the support staff. And winning most matches as captain is a collective effort, and credit goes to each and everyone," he said.
Man of the match Cheteshwar Pujara who scored a monumental double century said he was under pressure to perform despite being a prolific run getter in the domestic circuit.
"I just got married, and my wife was worried I should perform. We knew that the new ball would do a bit. The plan was to not lose any wickets in that first session," he said.
