A few nations are making a big mistake by trying to take advantage of the current mess that Board of Control for Cricket in India (BCCI) is in, warned former captain Ravi Shastri, who also advised the Indian board to demand every penny it deserves from ICC for being the biggest revenue generator.Shastri, who served as Team Director of the Indian team before Anil Kumble took over, warned certain cricket boards that this "institution is here to stay.""My warning to such people is: beware... This state of flux will not last for long. BCCI will be back where they belong very soon. And that is why it is important that the BCCI stresses on the issues at hand," Shastri said without taking any names.His apparent reference is it to England, New Zealand, Pakistan and South Africa. BCCI is undergoing sweeping changes due to Supreme Committee appointed Lodha Committee`s recommendations, resulting in removal of President Anurag Thakur and others.Source: Mid-Day
