The Mumbai Indians skipper has so far got only one wicket from seven Indian Premier League games, but Pollock feels it's just a matter of time before the senior off-spinner strikes form.
"Harbhajan sets very high standards for himself and his performance hasn't been that bad. Obviously, he hasn't got a lot wickets but that is not something we are worried about," Pollock said here ahead of Mumbai Indians match against Delhi Daredevils here tomorrow.
Asked whether Harbhajan was bowling a bit flat considering a bowlers limitations in Twenty20 cricket, Pollock tried to put things into perspective.
"It depends on what situation you are bowling and to whom you are bowling. There are times when he is coming to bowl with two set batsmen at the crease. It is difficult to throw the ball up in these situations as to when you are bowling to a new batsmen," the former South African captain said.
"But there is no doubt about the fact that he has played a lot of cricket here and knows the conditions very well."
