"You don't expect anything less from them in South African conditions. They have some new faces, a few young players, but with a lot of talent," the left-handed batsman added.
Duminy opined that India is a highly competitive side as they fought back to claim the inconsequential third Test, having lost the three-match Test series already.
"You are going to find that in white-ball cricket we will be closer competition. Even though we won the first two Test matches, India competed. That is what you want to see from high-profile teams. India are the No.1 ranked Test nation in the world, you expect nothing less from them. It's going to be a highly competitive series both in the ODI's and T20's," he said.
The former Test player said that the team will try to win the first ODI in order gain confidence and set themselves on top.
"The key for us is to start well. If we have a good game here at Kingsmead we can gain confidence moving forward. It will be different with six ODI's this time around, you have to win four matches to guarantee the series," he said.
