Indian Team Director Ravi Shastri today said that South Africa are still a formidable side despite the retirement of some big players recently, but his team will continue their aggressive brand of cricket in the upcoming series beginning on October 2.

"It is like asking me about Indian team without (Sachin) Tendulkar, VVS Laxman, Anil Kumble -- players will come and go, but you got to respect the fact that SA are world number one side," Shastri said at a press conference when asked about the visiting side who are coming without the likes of retired Jacques Kallis.

"South Africa are a stiff opposition. They play well in overseas conditions better than any other side in world cricket. They travelled better than any other team and records will show that. And so we what we are up against. The respect is there but we will not take any backward steps," he told reporters at the National Cricket Academy where Indian team is holding a camp.

South Africa are coming to India for a more than two-month long tour which begins with a limited overs series. India and South Africa begin the series with a Twenty20 International at Dharamsala on October 2.

The former India all-rounder brushed aside any talk of Mahendra Singh's possible rustiness to lead the side against South Africa in the limited over matches. India last played an ODI in June in Bangladesh and Dhoni -- who has retired from Test, led the side.

"No problem at all. You are talking about a season campaigner, one of the legends, one of the all-time greats in world cricket and not only of Indian cricket, you know I am saying as a captain. He (Dhoni) takes over a job he has been doing and so it is nothing new," Shastri said.
