It is lack of patience for kohli, in this series he gifted his wicket most of the times by playing bad and unnecessary shots.
The master of the art of living makes little distinction between his work and his play, his labor and his leisure, his mind and his body, his education and his recreation, his love and his religion. He hardly knows which is which; he simply pursues his vision of excellence in whatever he does, leaving others to decide whether he is working or playing. To him he is always doing both.
Hold on... thats just one inning.. that too after a long long time. MSD not at
all... Kohli lacks test temperament.
I disagree. He's played 14 tests, has 3 100s already and averages nearly 40. That's comparable to and even better than what players like Ponting and Tendulkar were at the same stage in their test careers. I believe Kohli has the skills to be a high quality test batsman.
