"Our bowlers bowled really well and the fielders backed it up", said Kohli. The fielding was fantastic and everyone was behind the bowlers. "It is refreshing to have such a talented bunch of players so we are very confident".
The fourth and fifth run outs by India in this tournament sent a shiver through the South Africans that they couldn't shake off.
"Through soft dismissals we lost our way and that was the part that hurt the most". Our bowling was alright i feel we could have done a whole lot better but they batted well and took their time.
"As a cricketer honestly for me personally, I crave games like this", Kohli told a press conference on Saturday.
ODI powerhouses India and South Africa are facing off in a virtual quarter-final in their final Group B clash at The Oval. The Protea openers began it steady but after Ashwin drew the first blood and dismissed Hashim Amla, the following batsmen also seemed hurry to return to the pavilion.
Though the overhead conditions were conducive for batting, South Africa retreated into their shell from the outset; preferring to play out the early overs instead of capitalising on the power play.
After opening batsman Rohit Sharma (12) fell to paceman Morkel, Dhawan and Kohli shared a second-wicket stand of 128 in 24.3 overs to hand India a comfortable victory.
Of course, their body frame is heftier compared to that of the diminutive duo of Bhuvneshwar Kumar and Jasprit Bumrah.
Bhuvneshwar Kumar (2/22 in 7.3 overs) was on a hat-trick as he not only polished off the tail, but also maintained a brilliant channel outside the off-stump, making life hard for the top-order batsmen. While Faf du Plessis added 36 from 50 balls, South Africa couldn't push the run rate into higher numbers, and India punished every single mistake the Proteas made.
Quinton de Kock  was at least providing some substance to his display, going to his 14th half-century before a mid-judged sweep saw him bowled by a quicker ball from Ravi Jadeja.
"A good toss to win, the wicket didn't change too much".
But Pakistan bounced back to beat top-ranked South Africa by 19 runs on Wednesday at Edgbaston.
Amla raised the tempo with a six over mid-wicket but, on 35, he tried to cut spinner Ravichandran Ashwin and nicked a sharp catch to wicketkeeper Mahendra Singh Dhoni.
Ravindra Jadeja struck the second blow for India when he knocked back de Kock's off-stump.
Gunathilaka is only in the squad as a replacement for the injured Chamara Kapugedera, while Kusal Perera had to pull out of the tournament this week after tearing his hamstring during that India game - Dhananjaya de Silva has been called up.
Unlike South Africa, Indian pacers bowled well in tandem.
