Youngsters Munaf Patel, Shanthakumaran Sreesanth and Vikram Singh performed well on the recent West Indies tour.

But chief selector Kiran More told the BBC: "We should have at least seven to eight such bowlers ready to play.

"With 40-50 one-dayers and quite a few Tests every year, it's important to have enough genuine fast bowlers. This will help us rotate them properly."

India's next assignment is a triangular one-day series in Sri Lanka, also involving South Africa.

And they will be looking for a return to form after losing 4-1 in the Caribbean, a result which was lost amid the celebrations of their 1-0 victory in the Tests.

"We will try and improve on the mistakes made in the last one-day series, but our plans for next year's World Cup will continue. We should not panic now," More commented.

There could be one or two changes for Sri Lanka, with More explaining: "Fringe players of the India A team could be a good choice for us - provided age is on their side.

"After all, experimentation can surprise the other team."

The Indian tour squad is due to be named on Thursday, with their first game against Sri Lanka on 16 August.
