London: Virat Kohli will be facing the toughest battle of his nascent One-Day International (ODI) captaincy career when defending champions India take on South Africa in a virtual quarterfinal of the ICC Champions Trophy, here on Sunday.
Their confidence shaken after Sri Lanka effortlessly out-batted them in a high-scoring encounter, the Indian team and Kohli in particular will be keen to ensure that South Africa are continued to be known as "chokers".

If India lose the game, the holders will be making an exit even before the semifinal. If the Proteas lose, then the current No.1 ranked ODI side would be ousted before the last four stage.
A defeat for India will have the skeptics blaming the speculated off-the-field issues for the exit.
In such a backdrop, Kohli will be under huge pressure with margin of error being next to nil.
For AB de Villiers, it will be an opportunity to prove that self-imposed exile from Tests has not affected his limited overs skills.
With three quality left-handers -- Quinton de Kock, J-P Duminy and David Miller -- in the South African line-up, Kohli can't afford to keep Ravichandran Ashwin out of the playing eleven.
More so after knowing what can happen to Ravindra Jadeja when there is absolutely nothing in the strip.
Ashwin has some natural variations, including the off-break which is his stock ball. The proud performer that he is, Ashwin will be smarting after being excluded from the first two games and it can only work positively in India's favor.
However, skipper Kohli's leadership acumen and understanding of the current situation will be under scrutiny depending upon the kind of playing XI he opts for the next game.
Ashwin's entry into the playing XI looks logical, but he certainly won't replace Jadeja as two spinners are likely to play against the Proteas, who are not known to be comfortable against slow bowlers.
The other big factor is Jadeja's electric fielding inside the circle and his powerful arm from the boundary line.
Neither can Hardik Pandya be dropped as his pyrotechnics at No. 7 are just what is needed from a batsman used as a floater in the order.
Jasprit Bumrah is another specialist bowler, who is a certainty in the playing XI, with his ability to bowl yorkers at will at the death.
Therefore it will either be Bhuvneshwar Kumar or Umesh Yadav, who may have to make way for Ashwin.
In the second Powerplay overs (11 to 40 ) during the Sri Lanka match, India conceded over 100 runs, something Ashwin will be asked to check as a marauding AB de Villiers will be itching to score big.
With scores of 319 and 323 in the two games, the Indian batting has a settled look.
All the top-order batsmen have got a decent hit, with the opening duo of Rohit-Sharma-Shikhar Dhawan having notched up back-to-back century partnerships.
While the openers have been in good nick, there's no denying that they have also consumed a lot of balls initially, which finally had an impact during the Lanka game.
With new Powerplay rules, any total of less than 340 can be knocked off with some positive intent on good batting wickets.
Kohli is happy with the batting performance, but on a practical note, feels that they may need 20 runs of cushion.
"May be you think of phases where we could have accelerated (vs SL), but I don't see that as a major issue. Maybe we will have to push harder now in the next few games to give us a 20-run cushion after seeing a result like this, because we're playing on the same ground as well," the skipper had said.
In fact, South Africa batting coach Neil McKenzie also agreed that fluency has been an issue for openers of all the teams.
"It's been a little bit tough going for the openers. The fluency has been an issue. But one needs to adapt according to situations as the conditions here demand little bit of caution. The wickets need to be kept so that one can attack in the back end," McKenzie said.
On the personal front, Kohli himself would like to lead with the bat against a side that has bowlers like Morne Morkel and all-rounder Chris Morris.
Imran Tahir, whose stock ball is googly, might just test Rohit's defense as the Mumbaikar had some trouble reading the wrong 'un from him during the IPL.
One can brace up for some exhilarating action between two quality sides.
