Kolkata: India’s head coach Ravi Shastri has said there are “plenty of questions” to be answered on the behaviour of the pink ball as Virat Kohli and his teammates faced Bangladesh in the day/night Test today (November 22).

Both India and Bangladesh are playing their first-ever pink ball Test. However, they are concerns over how the pink ball behaves. Shastri too spoke about it.

“(It's a) historic occasion, boys will look forward to it. There will be a wait-and-watch game as well,” Shastri told the host broadcaster Star Sports ahead of the first day’s play at Eden Gardens on Friday.

“Plenty of questions to be answered and time will tell," he added.

This is the 12th day/night Test match in the world. It was first played in 2015 between Australia and New Zealand. Australia have so far been unbeaten in pink ball Tests winning all five.

“Adapting to pink ball will be a challenge, we've got to see how the ball will behave, how close will it be to how Test cricket should be. It seems a little harder and heavier than the red ball,” he said.

“So when you're catching, you have to watch it that much closely into the hand. Only time will tell how it behaves, how it will handle dew, how much of swing there is, how much of reverse, how much will it help spinners,” he explained.
