You don't know the fall of Krish, when bowler like Vasim Akram knew his weakness and he was bowled many times at zero to 10, mostly in the hands of Akram. Even One bouncer hit him to his head. He frightened to face boucer from left hand bowler afterwards and it goes till his career's end.
U cannot blame coach for every thing.
U cannot blame that your teacher is/was not good when you are not performing at your exams. Make also yourself responsible and only hardwork, proper planning and its execution only wins. Agains Bangladesh, the game was not planned properly by Indian cricket team.
Also, If same team brings the world cup, you will never say or bring your word back. So keep cool.
We cannot make a cricket as khilona in the hands of other.
