Kolkata: Bangladesh's spin bowling consultant Daniel Vettori conceded that early sunset in Kolkata could pose a massive challenge for his team's batsmen during the "twilight" hours of the upcoming historic Day-Night Test against India starting on Friday.
While a handful of first team players from India have played pink-ball game in domestic cricket, Bangladesh's only experience with the pink ball was a one-off Day/Night four-day match in 2013 but none of the current team players were part of that fixture.
"I think the pink ball is relatively normal in the day, the challenge will be how much of the Test is played under lights. Obviously, the sun sets quite early here. I think 4:30 pm. That will be the time we will see the pink ball come into play," the former New Zealand captain said.
Vettori has not been a part of any Day/Night Test venture but from the experience he feels batting during twilight period will be challenging.
"My experience is only from watching on TV and it seems to do a little bit more during twilight dusk. So I think that's going to be a big sighting period of the Test match. That'll be the period of the Test the teams will try to do technically a few different things. I think that the final one and a half session would be very interesting."
With the pink ball expected to help seamers more, Indian captain Virat Kohli is expecting complete his 12th straight home series win with ease.
Vettori however said Bangladesh pacers are equally excited with the team boasting leftarm pacer Mustafizur Rahman who sat out in Indore.
"All fast bowlers are really excited. Coming to grips with the balls, I think the SG pink ball is slightly a bit different. Most guys have limited experience of Kookaburra ones. I think there's a lot of excitement and optimism around.

Both Rohit (left hamstring) and Ishant (side strain) are at the NCA undergoing rehabilitation, but the BCCI is yet to announce when the duo would reach Australia.
The duo played for the Royal Challengers Bangalore team and Zampa, who is in Australia's limited-overs squad for the upcoming ODI and T20 series against India starting on Friday, said he forged a bond with Kohli over meat-free eating, coffee and cricket.
Kohli, who is heading family way in January, will be returning after playing the six white ball games and the opening day/night Test scheduled in Adelaide.
