Image Source: ICC[/caption] Internet Desk: India will face World No.1 side South Africa in an unofficial ‘quarter-final match in the ICC Champions Trophy tomorrow. According to India skipper Virat Kohli his team doesn’t need to be over-excited against the Proteas and the team which will have better composure on the match day will have a better chance of winning of the game. "You need to have a good balance of being competitive and being passionate and at the same time not getting over-excited. I think the team that treats the game as normal as possible are in a better position to get the right result," said Kohli at the pre-match press-conference. "Lot of times, teams try to do something special and end up messing the game up in important situations. The team that will have better composure will have a better chance in winning the match tomorrow (Sunday). That it what I have experienced in the past." South Africa have three left-handers in the top order, such as Quinton de Kock, Jean Paul Duminy and David Miller. Ace Indian off-spinner Ravichandran Ashwin could be a good option in such conditions against the left handers. Kohli though didn’t say anything and said that the team management is discussing on all possible options. "There are all kinds of possibilities. We definitely have looked at the last game and where we can make a bit of a change. We have already discussed those things. But I am not going to reveal anything now," said the India skipper. Yuvraj Singh smashed a brilliant half century against arch-rivals Pakistan in their first match of the ICC Champions Trophy and he will play his 299th ODI match tomorrow. Skipper Kohli and Yuvraj Singh played a lot of cricket together for India. On being asked about his experience with the fiery left-hand Batsman Kohli said,” He's achieved tremendous things for India, two Man-of-the-Tournaments in World Cups, India winning both, is a very special achievement. And personally in his life, as well, he's fought with bigger battles and that's a proof of the character that he possesses and the temperament that he has. I wish him all the best for tomorrow, and many more games that he will play for India.” Proteas skipper AB de Villiers failed to do anything till now in the ICC Champions Trophy. According to Kohli it happens with all the cricketers and he will come back to his form at any point of time. “I empathise with him. I go through this a lot, as well. When you have set standards for yourself and then people get shocked. You know, he's by far the most coveted cricketer I've ever seen around, and the reason for that was trying to do something extra for his team and that's the kind of character he's always been. “So, yeah, I'm not -- I wouldn't say I'm shocked. I know AB quite well, so I know the reason behind, you know, his mindset of playing like that. Yeah, but at the same time, he can come out and when he's in the right frame of mind and on his day and he's in the mood; then it doesn't matter what he's done in the past games or how many runs he's scored or not scored. If he decides to play the way he can, you know you have to find a way to get him out pretty quickly, said Kohli.
