India entered the quadrennial extravaganza following a winless tour Down Under and the defending champions were far from being called favourites to retain the title.
However, Mahendra Singh Dhoni's outfit proved their credentials with two convincing wins against arch-rivals Pakistan and a strong South African team. They have won all their three matches so far with emphatic margins and are now almost certain to qualify for the quarter-finals as the top team from Group-B.
"It was a case of performing to their potential and that's exactly what has happened in the two matches against Pakistan and South Africa. If you ask me, the script went on expected lines," the former Indian captain said.
According to him, the break after a disastrous tri-series campaign, which came on the back of 0-2 defeat in the Test rubber, did the trick for the Men in Blue.
Besides batting and bowling, the Indian fielders have caught the eye with their athleticism on the field, prompting Shastri to go to the extent of calling them one of fittest units in the world. He said this in relation to a question on the 1985 victorious campaign in the Benson & Hedges World Championship, where the former all-rounder was at the forefront.
