India rode on Kohli's brilliant 138 to post 299 for eight and then restricted the visitors to 264 for nine, despite a valiant ton by rival skipper AB de Villiers to win by 35 runs and level the five-match series 2-2.
"Virat is someone always keen on improving his game. Even when he would get out scoring a 60 or a 70, he wanted to convert it into a hundred. The way he paced from 50 to 60 and then from 100 to 110, this is the bracket when most batsmen get out. Once he crosses that mark, he'll always play a big innings because that's his mindset," said Dhoni at the post-match press conference here last night.
"He was rotating the strike really well. Also, the important thing is when you play such a long innings, the middle overs -- putting pressure on the fielders is the key," he said.
"If you can freely rotate...That's one area where we have to improve as a team, especially with the kind of reverse swing the opposition gets. They can cramp us and have a fielder close to the umpire and mid-wicket. If both batsmen can do it, it eases off the pressure," he added.
"Our spinners bowled well and applied pressure. Harbhajan bowled well in the powerplay and later. He also did well in the middle overs. He is someone who is very experienced. He has done well in IPL also. He has the experience and has been bowling well as of now," he said.
"We always assess bowling in terms of wickets. But a lot of times, especially being the wicketkeeper, you have the advantage of seeing what a bowler is doing and how much he's extracting from the wicket. I feel he's bowling really well," he added.
