Soon after making an instant impact in his maiden Test on Australian soil, India spinner Kuldeep Yadav said he needs "more time" to improve as a Test bowler, stressing that playing red-ball cricket is vital for his growth.
The 24-year-old left-arm wrist spinner scalped three wickets to leave Australia struggling for 236-6 on the third day of the fourth Test.
Playing in his first overseas Test since Lord's, Kuldeep said he was a bit nervous.
"To be very honest I haven't changed anything (for bowling in Australia). I am playing my first Test in this series and so was nervous," he said on Saturday.
"I have played enough cricket to have decent enough knowledge but in Test cricket I will need a little more time perhaps to improve. The more you play with red ball the more you can improve."
Kuldeep said there is no substitute to "match experience" when it comes to improving as a bowler.
"Test cricket is similar - the more you play the better you can read batsmen. There is time enough to plan for batsmen, you can bowl more overs and change fields," he added.
"There is more pressure (when you play red ball cricket after white ball cricket) ... You need atleast 10 days as a leg spinner to change your mind set and control things.
"If you are bowling in the nets you can improve a bit but if you are playing more matches, you improve more. You need match practice, because four-day and Test cricket is very different from ODIs."
Dropped midway through the England series, Kuldeep said he is motivated to fight for his spot with the presence of R Ashwin and Ravindra Jadeja already in the side.
"When you know you have Ashwin and Jadeja, best spinners in the world, and you are the third one, so then there is a lot to motivate yourself and learn from them. They keep pushing me in the nets that you have to bowl this way and in good areas. "So I am very motivated (to play) and it is important to learn from them because they have played enough cricket. I am still learning."
