Virat Kohli needs to practice more to adjust his eyesight, improve reflexes, says Kapil Dev

New Delhi: Kapil Dev feels slowing down of reflexes could be the reason behind Virat Kohli's struggles in New Zealand and the Indian skipper needs to "practice more" to overcome the age factor.

The 31-year-old Kohli managed just 38 runs in the two Tests at an average of 9.50 in New Zealand. In the preceding limited overs series, he managed to score 180 runs including a half century, making it a forgettable tour for the India skipper.

"With every big batsman there comes a phase. This is the age, after turning 30 everyone says there is a dip in the eyesight and that takes 6 months to a year to get used to it," Dev told ABP news.
