Improved Bangladesh 'no cakewalk', says India's Rohit Sharma

All-format captain Rohit, 35, is returning after being rested for last month's 50-over series in New Zealand, which they lost 1-0.

"It's going to be an exciting series," Rohit told reporters.

"They are playing in their own backyard so we expect them to challenge us in every bit - batting, bowling and fielding," he said. "So we have to be at our best."

India have a lifetime 30-5 lead over the hosts in 50-overs matches but lost their last series tour of Bangladesh 2-1 in 2015.

Rohit said Bangladesh have evolved into a "different team" since then and could be expected to put up a strong fight.

"They are a very challenging team and we have not had easy wins against them," he said. "By no means do we come here thinking it's going to be a cakewalk for us."

Big guns Virat Kohli and KL Rahul also took time off from the New Zealand tour.

Rohit and Kohli, 34, have taken regular breaks in recent times to manage their workload.

"It's impossible in this day and age that you will play with your best 15, it's not going to happen," Rohit said. "You will always need to rotate and see the best you can get from your players."

With India hosting the ODI World Cup next year, every 50-over match will be seen as preparation for the showpiece event but Rohit said the tournament is not on their minds.

"We can't think so far ahead but we will keep an eye on where we can improve as a team and see how it comes along for us," he said.

He and coach Rahul Dravid "have a fair idea of what we need to do and we will narrow it down once we get closer to the World Cup," he said.
