Lehmann said Ishant, who did not figure in the victorious Indian World Cup team, had problems of overstepping initially, but once that problem was solved, he has made steady progress.

"He had issues, early in the tournament, with no balls. We sorted that out and he's bowling beautiful length and with good pace. He trains as hard as anyone. I have not seen a fast bowler, train and recover so well. His preparation is second to none," he said in praise of Ishant.

"If he is not in the Indian team, then I am a poor selector. He's been unbelievable this year," Lehmann added about Ishant who flattened Kochi Tuskers Kerala in the latter's backyard with incisive figures of five for 12.

Lehmann was also impressed with another India pacer Munaf Patel who plays for rivals Mumbai Indians.

"He's bowled very well in the World Cup. I think he's more consistent with his length and line, more so than anything else. I think he and Ishant are the two bowlers who will take Indian bowling a long way," said the Aussie who also praised the overall strength of the Indian squad.

"India has a very good squad and that's what makes a successful team for a long period of time," he remarked.

Talking about the Chargers' poor display in IPL-4 that has pushed them to the bottom of the table, Lehmann said the team had talented players but could not click as a unit.

"It's been frustrating for sure. We have not been far off from playing pretty good cricket. We lost six games, which actually we should have won. We have lost by ten runs, missed here and there and dropped a couple of catches. We have lost the big moments.

"We have a good batch of overseas players and some good local kids. I don't think they (batsmen and bowlers) have clicked together. When they have we have won games comfortably," he added.
