"Time is on my side; I am still very young and there is a lot of cricket left in me. I have to start doing even better for Team India and start taking a lot of wickets. If I keep myself fit, I will be able to do it.
"It's not easy to take even one wicket in international cricket. Batsmen are watching you all the time. You have to keep adding variations. Just line and length is not enough. You have to make sure you are not left behind. Off-spinners now are coming to bowl from round the wicket. You have to keep trying new things," Harbhajan said.
"Batsmen these days come and play their shots. I remember 10 years back, all the bowlers were averaging 25, 26 or 27. These days the normal average is 30 plus.
"When I have my good days, I take wickets. On bad days, I try not to give too many runs," he added.
