Kolkata, Sep 29 (IANS): A rare run drought over the last three innings does not bother Virat Kohli, the Indian Test captain said on Thursday.

"I don't think about these things. Cricket is a game where you can only prepare well. Results cannot be in your hand all the time. You get caught to a no-ball and different things can happen which are out of your control," Kohli said at a media briefing ahead of India's second Test against New Zealand starting at the Eden Gardens on Friday.

"Preparation is something that is in my hand and I look to do that every time I walk in to practice," said Kohli, who has averaged 26 in the last three essays after his double century in the first Test in the West Indies.

The 27-year-old batsman said he doesn't believe in form.

"I don't think there is anything called 'form'. It is how you are feeling on a certain day. It always doesn't mean you are out of form. It's just about how you are feeling mentally on a given day. We want to understand what we want to achieve and be stable in our head. I am looking to work hard," Kohli said.

On whether the Decision Review System (DRS) should be implemented by the Board of Control for Cricket in India (BCCI) after Kiwi captain Kane Williamson nicked a caught-behind in the first innings of the series opener at Kanpur, which was not given, Kohli said, "Those are the things I can't say yes or no sitting here. These are things we had discussed and had a meeting."

"Some things can be debated like ball tracking and hawk eye. I personally feel these are things that can be debated on. We don't have DRS, so we cannot blame umpires. Once DRS is in place, then we can think about it."
