Virat Kohli believes India failed to apply enough pressure to England as they fell to defeat in the first Test in Chennai.
England secured a 227-run success to take a 1-0 series lead after another confident display away from home.
Joe Root’s brilliant first innings double century laid the perfect foundations for the win – just a second defeat on home soil for India in eight years.
James Anderson (3-17) and Jack Leach (4-76) then bowled the visitors to victory on the final day.
India skipper Kohli felt his side could have piled more pressure on the tourists.
“We didn't put enough pressure on England,” he told BBC Sport. “At the end of the day, it is the mindset of if you feel good, you can bat well and bowl well, and that is something we need to get back into.
“There will be hiccups, but we are always a side that are looking to improve. We'll be looking to bounce back.”
India must now show the same battling qualities they displayed to land their recent comeback success in Australia.
A 2-1 or 3-1 series win for India against England will be enough for them to secure a place in the final of the ICC World Test Championship.
Root Pleased with ‘Exceptional’ England
Meanwhile, England captain Joe Root hailed the victory.
He said “This win will be right up there. It was always important to start well, India will have been full of confidence on the back of their achievements in Australia and are at fine team at home but for us to perform like we did was exceptional.
“I don't think we were perfect, we could do things slightly better and that's an exciting place to be.”
India could look to change their second spin option ahead of the second Test with Kuldeep Yadav a possible replacement for Shahbaz Nadeem.
England will be without wicketkeeper Jos Buttler, who will be rested for the remainder of the series. Ben Foakes is likely to take the gloves.
Root and the England backroom staff will also have to decide if to bring back Stuart Broad for James Anderson with the 2nd Test starting on Saturday.
