Former India skipper Rahul Dravid has thrown his weight behind the beleaguered Mahendra Singh Dhoni, saying that he is the "only man" capable of leading the Test team but should quit Twenty20 captaincy to avoid becoming "stale".

"Not only is Dhoni the only man to lead India in Test cricket, he is still capable of doing the job well. What it will require from him is a change in the way he captains, a recognition that he can't do everything all the time, and the willingness to ask for and accept help," Dravid said.
