India recorded a 3-1 series victory over England on Saturday, ending the fourth and final test inside three days.
India’s 13th consecutive test series victory at home also secured their place in the June final of the World Test Championship against New Zealand.
In a sign of India’s strength, they won the last two matches in a total of five days at Ahmedabad’s Narendra Modi Stadium.
Once again, Ravichandran Ashwin and Axar Patel were the architects of their victory by an innings and 25 runs in the final match.
The spinners took all 10 wickets in England’s second innings. They finished the series with a combined haul of 59 wickets, even though Patel did not play the opening test which England won.
“The first game was a bit of an aberration, just a hiccup, when England outplayed us,” Kohli said.
“You’re obviously happy when you’re winning so many series but there are always things to improve, like after the first game in Chennai we had to pick up our body language.”
After a below-par 205 in the first innings, England needed a vastly-improved batting performance in the second to stay alive, but their frontline batsmen let them down again.
Barring Dan Lawrence, who scored 46 and 50, the rest looked scarred from their struggles against spin in the previous match at the same venue.
Jonny Bairstow registered his third duck in four innings, which may render his place in England’s test squad untenable.
Root finished as the top-scorer in the series following his 218 in the first test, but it was otherwise a miserable batting display by his side.
England crossed the 200-mark only twice in eight innings and repeatedly rejigged their combination.
India exploited their home advantage to win three matches in a row.
Ashwin’s all-round brilliance helped level the series in Chennai and Patel bowled them to victory inside two days in the third match in Ahmedabad.
Rishabh Pant turned the final test with a match-winning century before the spinners completed the rout.
From March 12 onwards both play a five-match Twenty20 series followed by three one-day internationals.
