We had a chance to beat Australia in the WC2003. Tendulkar, Gavaskar's favorite batsman and the next Don Bradman, did not even make a fifty let alone try to make one.
You can only take a horse to the pond, you cannot make it drink water. You can only tell the players to improve their run up, batting stance, coordination, you cannot put the spirit in them to fight for their country.
Tendulkar in particular needs a session with Javed Miandad to know what playing for the country means.
