The Coach can only correct a wrong line of thinking and give his inputs for the betterment of players technique, temperament, skill and confidence.
The XI men in return, need to perform on the field and bring the laurels to the Nation, by the weight of their ability, performance, skill and tactics.
So if the Team does not perform, then all of them should accept failure and take responsibility and blame equally.
Why blame the coach alone and protect the players from the axe ????
