The Indian team's tough tour of England will begin with the three-match T20I series.
"I am not surprised with the way Jos has played", he said. "No one can guarantee results, just wanting to win every session and every ball that we play".
Sundar is likely to be replaced by Krunal Pandya for the T20I series and Axar Patel for ODI series.
Buttler carried stunning IPL form, which saw him hit five consecutive half-centuries for his franchise, into England's global season, nailing his Test recall then starring against Australia in the ODI series.
And on a flat surface, perhaps more Mumbai than Manchester after being baked by the recent hot weather, England will hope this does not set a precedent for the tourists feeling very much at home over the next three months.
To start off the series, the Indian team management is to go in for set combinations.
In the absence of Jasprit Bumrah, Umesh Yadav in all likelihood will be part of the playing XI. If we win the crucial moments, then anything can happen on the day. We want to play competitive cricket.More news: Neymar inspires and infuriates as Brazil beat Mexico to make quarter-finals
India present a much stiffer test than a weakened Australia.
India are coming into the series with two facile victories over Ireland - by 72 and 143 runs respectively but Kohli knows too well that England will be a different proposition.
Most sports fans across the globe, let alone English fans, will probably watch England taking on Colombia in the Round of 16 tie of Fifa World Cup 2018 in Moscow on Tuesday, July 3. And Virat Kohli has taken the chatter down an unexpected road, talking about barriers being broken, warmth being felt, and relationships being fostered between the players of the two sides.
Kohli's skill with the bat is not in question, even if there remains a slight question mark about his ability in red-ball cricket here with an average of 13.40 compared to his overall average of 53.40. It does not matter whether I get runs or don't get runs.
"Take away from this tour will obviously be the way we play our cricket, the mindset and attitude we maintain for the length of the tour that we play".
"We all are feeling relaxed and having a good time". While Chris Jordan was the third man out first ball - caught and bowled by Umesh Yadav off his pad - David Willey was in no mood to go down with a whimper, blasting 29 from 15 balls, adding a touch of fight in some verbals with Bhuvneshwar Kumar, and an early breakthrough in the chase when Shikhar Dhawan played on in the first over. The openers Jonny Bairstow and Jason Roy have been in tremendous form and will look to continue the same form against the strong side. Virat Kohli and MS Dhoni are certain to feature in the XI and it'll be among Manish Pandey, Dinesh Karthik, Suresh Raina, and KL Rahul that they'll be choosing any 2.
