"It happens in some series but there is nothing to worry about. We are world champions after all and we will be back in our elements soon," said Harbhajan.

"It is true that we have not performed well but it happens in cricket. I am sure the team will be back to form soon and give a tough fight to all its opponents," he added.

India were humiliated 0-4 by Australia in one of most lopsided Test series in recent memory, barely six months after England handed them a similar thrashing.

The 31-year-old Harbhajan, who was not picked for the just-concluded series, said he is hoping to make a comeback very soon.

"I am doing what I am supposed to do. I am hopeful of playing in the national team as I am ready for a comeback. I have worked very hard to improve my game," he said.
