The former India star is the leading Test and ODI run-scorer of all time, and is widely regarded as one of the game's greatest-ever batsmen.
England, 1-0 up in the five-match series after an absorbing 31-run win at Edgbaston last week, will hand a debut to 20-year-old Surrey batsman Ollie Pope after dropping the out-of-form Dawid Malan.
"We've got a 12".
"Then we need some composure", he added.
England might have settled on one of their two selectorial decisions, the other will be decided on the first morning, a straight shootout between Moeen Ali and Chris Woakes, with Jamie Porter released from the original squad of 13. It has taken the Indian captain 37 games to play the same team in two back-to-back Test matches.
Despite the issues with the batting order, Kohli remains upbeat about his team's chances of levelling the series when the match gets under way on Thursday.More news: Star Witness Gates Testifies He Committed Crimes With Manafort
"I know that might be seen as quite a big jump".
"I think Steve Smith is probably the hungriest batsman but he's obviously not playing for 12 months, so Kohli really is the premier batsman in world cricket".
After the pulsating drama of last week's opener in Birmingham, expectations for Lord's remain high, but with a series fascinatingly poised, five days of glorious sunshine forecast and a bountiful crop of intrigue both on and off the pitch, you wouldn't bet against it delivering.
Yet this season has seen Pope make 684 runs for Championship leaders Surrey at an average of 85.5, including three centuries. "He's very mature for a young man", said Root.
After scoring his maiden ton on the English soil, Kohli returned in the second innings and played a 51-run knock to steer India closer to the 194 runs target set by England.
As for India needing more runs from their batsmen, Arun said: "If you look at the (Edgbaston) scores, it's only Virat Kohli and Joe Root who have been able to contend with the moving ball. The challenge is there for us to adapt even better and we have our plans in place".
