India won the four-Test series 3-0, with the second match at Bangalore being washed out. While India won the first and third matches within three days, the last Test here went on till the fifth day with South Africa putting up a massive resistance for the major part of the match.
"All the wins were special, but this one is more because we had to work harder. The South African batsmen put their heads down and played for the draw, always hard work. I just asked the bowlers to put their hands up and that's what happened after tea," said Kohli at the post-match presentation ceremony.
Kohli said it was important to back the bowlers.
"We have bowlers who have the pace, it is important to back them on any surface. It is important to give them confidence at the right times and they have to respond as well and that they did," he insisted.

"I just want to thank the crowd, it has been tremendous playing in front of a packed stadium. Thank you for all your support," said Kohli.
Twin centurion of this Test, Ajinkya Rahane bagged the Man of the match award for his efforts and said he backed himself to do well.
Asked about his two centuries in two innings, Rahane said, "Really enjoyed that. Really happy for myself and my team."
The Man of the series, Ravichandra Ashwin, who took 31 wickets in the series and also scored some valuable runs, said winning this Test was a fitting finale to a wonderful series.
Ashwin said he got huge support from Ravindra Jadeja at the other end.
"There's not much bounce. I got massive support from Jadeja, he hits the stumps so often. It was an amazing support from me, and let's not forget Umesh (Yadav), who also bowled very well today," he said.
Meanwhile, South Africa skipper Hashim Amla applauded his players' efforts for putting up a fight in the last Test here.
"We knew we had to bat long and hard, we tried our exceptional best. AB (de Villiers) had a fantastic effort. You got to do what is best for the team, it is easy to go out there and get some runs, but we tried to take it as deep as possible, get something from this game.
He, however, said that his batsmen failed during the Test series.
"Winning the T20s and the ODIs was brilliant. As a whole, we managed to have some success. It was a good learning experience for the youngsters in the team.
"Test series was tough for our batsmen, we didn't get enough runs. Credit to our seamers on these pitches, just unfortunate we couldn't get the runs to back them up," said Amla.
