"I have been very impressed with Umesh (Yadav) since he came back (from injury). He has been bowling quick and has also been consistent, not inconsistent any more," said Kohli ahead of the second ODI tomorrow.
"He's hitting good areas with good pace and that's giving the batsmen trouble on flat wickets like the other day as well in Delhi against the West Indies (in the abandoned series) when his opening spell was really nice. He's working on his death bowling as well," said Kohli.
"Coming closer to the World Cup it's great to see all these guys bowling really well as a stronger pace attack in Australia will give us an added advantage," said the stylish batsman.
Kohli also praised the batting, India's strongest suit for years, and said the idea was to try out different players in different batting positions in the ongoing five-match series.
"It's obviously keeping in mind that those guys are good enough to play in those positions and able to win those games for us. It's all about infusing that confidence into people and they will end up giving you the result. So this is just a phase leading up to the World Cup," said Kohli.
