"There is a lot of grass covering it. There was also help for seamers. We were not sure what kind of wicket it will be and what will be a defendable total," said Harbhajan.
"This was the same case with CSK as well. When I was talking to Dhoni, he was telling me the same. The ball swung more in the evening than when we started the game," he added.
The Super Kings, who were all out for 112, were banking on skipper Dhoni to do the rescue act after the well-set Suresh Raina and Dwayne Bravo fell in quick successions but Dhoni got run out and Harbhajan believes it was the turning point of the match.
"At one time Chennai were going strong. Dhoni's wicket was the game changing thing for us. We stuck to our plans when Raina was batting. They were going strong. After getting Raina, we were right on the target with the ball.
Harbhajan also heaped praise on Richard Levy, who scored 35-ball 50, saying he wanted him to keep up the good work.
"He is a terrific player. His strength is that he can hit the ball hard and score quickly and that is why we picked him."
Sachin Tendulkar sustained a finger injury in his left hand and retired hurt when he tried to fend off a rising delivery from the Super Kings' bowler Doug Bollinger and Harbhajan said he was hoping it was nothing major.
"At the moment he is fine. His finger is little bit bruised. I'm keeping my fingers crossed that he will be fine and ready for the next game," said the captain.
