India`s stalwart batter, Virat Kohli, disclosed that he wasn`t confident about delivering a performance in the T20 World Cup final in Barbados. Before the final, in seven matches, Kohli, with all his experience, struggled to find that elusive purple patch and put together a string of performances that he enjoyed in the Indian Premier League. Before the final, he could only muster up just 75 runs at an average of 10.71, which was well below the standards that he had set over the years. But in the final against South Africa, when the Indian team needed him the most, Kohli tapped into his prime and brought the best out of himself, proving that `form is temporary and class is permanent`.
