"It is the toughest to bowl against batsmen who you do not have an idea about. You do not know their style of play and what kind of strokes they play to score their runs, hence it is challenging," Harbhajan said.
"Whatever videos I get to see of such batsmen, I try to analyse that part of it and bowl my best balls to them when I face them," he said.
"I try to keep things as simple as possible. I take the game one step at a time. I always feel I have to bowl according to the situation of the team. I back myself whether I am bowling up front or bowling in the middle of the innings or bowling at the death," the off-spinner told iplt20.Com after the match.
Harbhajan said he backs himself to pick wickets on batting friendly pitches despite going for runs.
"You have to keep believing in yourself as a bowler that even if you go for runs, you can pick up wickets. You have to back yourself and bowl accordingly," he added.
