indian player are not that small to b spoon feeded they know wht is good and wht is bad. the job of the coach is to just show the direction and the rest all depends on how the players perform. Im not saying tht u people r wrong ,but bcoz of ur possesiveness for our team u r thinking this, try to to see other side of the coin. no teacher will teach wrong i suppose.
consider an eg of school/college teacher she/he does their duty by teaching but if students r unable to clear, it does`nt mean tht teacher thought wrong.
