Congratulating the master blaster, Hazare said he expects Tendulkar to raise voice against corruption inside Parliament like the way Team Anna did outside it.
"We welcome and congratulate him. Sachin should raise his voice against corruption and also in favour of the Lokpal issue. We will keep supporting him from outside," he said.
Team Anna member Santosh Hegde, however, said he did not think that the group was expecting anything from the 39-year-old cricketer.
"I, as a member of Team Anna, wish him all the best," he said.
Arvind Kejriwal said the group would request Tendulkar to make efforts to bring a strong law against corruption in the Rajya Sabha.
Tendulkar, who was nominated to the Rajya Sabha by the government on April 26, took oath as a member on Monday.
