There are many experienced players in the India team that New Zealand men's side will be wary of in the Champions Trophy final. But one of their most inexperienced players will also loom large on the minds of New Zealand's batters.

"I think guys will be better for the run against Varun. He's obviously a world-class bowler we've seen it here and in the IPL. He's got that little bit of mystery. But it was the first time some of the guys have been facing him. I think they'll learn from the other day."

Santner got a particularly vicious delivery from Chakravarthy in the group match, one that was flat and fast, and yet took substantial turn to take out his off stump.

"If the pitch plays a similar way, it's going to be a challenge along with all three of their other spinners. I think the boys will be ready for tomorrow having looked at a little bit more footage. We know what his threats are now. That 115kph arm ball, that got me - that was a bit of a threat."

While Chakravarthy is India's top spin-bowling wicket-taker in the tournament, their other three spinners have also prospered on a turning Dubai track. Axar Patel has five wickets for the tournament, and Kuldeep Yadav and Ravindra Jadeja have four each. They had been effective through the middle in that previous game against New Zealand.

"I think the way Axar and Jadeja denied us for a long time, it might be something similar again on a slow wicket, where it's as if you can kind of just rotate and hit the odd bad ball away, you can get yourself up to a decent score," Santner said.

"We've got some good players of spin and it's about them trying to just play their games and whether it's to get your broom out and sweep, or it's to use your feet, I guess we kind of give our players the freedom to play their own way."

New Zealand have their own quartet of spinners, in Santner himself, Michael Bracewell, Glenn Phillips, and Rachin Ravindra.

"On the flipside, it's the same with us. For us it's about trying to build pressure for a long period of time to produce a false shot."
