India lost the first two ODIs of the ongoing three-match series to allow Bangladesh take an unassailable 2-0 lead and captain Dhoni received a lot of flak.
"If you don't go behind your leader (now) then when will you? So as far as I am concerned it's like an army, if you don't go behind your leader then you are definitely going to get shot. If my captain asks me to die on the field, I'll do it," Ashwin said in a media conference.
Calling Dhoni one of the legends of Indian cricket, Ashwin said: "He is one of star cricketers. He has done so much for the nation. We can't really forget what he has done.
"Yes, I know bad results crop and all kinds of statistics crop up. With statistics you can prove whatever you want as you please. You have to give credit to the individual because he has done a lot of good things.

Although Ashwin admitted that India did not play good cricket, he said that the dressing room atmosphere is exactly the same as it has always been.
"I think we should be honest in admitting the fact that we haven't played very flamboyant cricket, and we have not come out of our shell. But as a whole, the dressing room atmosphere hasn't been anything short of anything it has been in the past. I think we are used to the fact that we do lose a few, but we win more, which has kept us in good stead.
