"We know that complacency could creep in, we are very much aware of such a situation. We have to play every match like a semifinal or a final and try to give our best," the South African said ahead of his side penultimate league match against second-placed RCB here tomorrow.
He also ruled out wholesale changes in the playing eleven and said the team will have a nice blend of youth and experience in tomorrow's match.
"It would be a mixture of both experimentation and sticking to some of the tried and tested combinations. It is an ideal opportunity for a couple of guys to get their turn," said Duminy.
Duminy also said that he was disappointed to miss the first nine games of Mumbai Indians.
"It has been a great tournament and an unbelievable experience. The atmosphere out there at the ground is electric. I am disappointed that I have not played a major role this season," he said.
Duminy was of the view that there was no room for a specialist wicket-keeper in the shortest format of the game.
"I don't think there is a place for a specialist wicket-keeper in Twenty20s. Look at the Bangalore team, Robin Uthappa is keeping the wickets though he is not a regular wicket-keeper. It is just a 20-over game and you need to have a strong batting line-up," he said.
