Cricket's poster boy Mahendra Singh Dhoni described the forthcoming series against South Africa as tough and said he was focussed on giving his best on his maiden visit to the Rainbow Nation.
"I have been working hard to perform 100 percent there under different situations and conditions," Dhoni said when asked about his recent batting performance.
He said he was put on a different slot in the batting order as per the team's requirement earlier, but in the recent past he was batting at number seven.
"The change in the batting position has certainly put more responsibility on me as I have to score more runs in less number of overs," he replied when asked to remark on his new position.
The inclusion of Dinesh Karthik in the squad for the South Africa tour would provide for more competition, he said.
Still preferring the middle-order batting, Dhoni said he would strive to maintain cent per cent strike rate in the new position to score more runs.
When his attention was drawn about questions being raised over his role behind the stumps in recent times, Dhoni said, "Up and downs are part and parcel of the game, but certainly I am working hard to improve before the World Cup."
