Dhoni was also candid enough to admit that the bowlers were grappling with issues like bowling at the death and slow over-rate, which incurred the India captain a two-match ban during the ODI series against the Lankans.
"We struggled early in the series but improved a lot in the later matches. We have struggled a bit in the death overs but if we can do something
in patches, we can do it consistently as well. We can restrict any good side to a decent total. It's slightly improving but I think we can manage it," Dhoni said.
