3. Navdeep Saini:

The youngster after impressing during the limited-over formats earned the maiden call-up in the Test series. On the bouncy pitches of New Zealand, his ability to clock 140 kph might be an advantage for visitors. But Virat Kohli would like to go with the experience of Ishant Sharma, Mohammed Shami and Jasprit Bumrah.
Indian skipper would like to end the series on a winning note after facing defeat in the three-match ODI series. And also, this series is the part of ICC Test Championship so gaining points will be important for the team to maintain the top position.
Therefore, the 27-year-old might have to wait to make the debut in the longest format of cricket.
