Lehmann is happy with the progress made by a young Australia team under the guidance of Smith and himself but admitted to being disappointed at missing out on a series win.
The coach added: “They have been excellent. There have been difficult conditions there is no doubt about it. They haven’t whinged once, they’ve been just getting on with the game.
“They’ve copped a lot from Indian media and that’s just the way it is over here. I’ve been pleased the way they have handled it.
“We have decided we are going a different way about the way we play. Obviously we’re less aggressive than we have been in the past. And I’m pleased with the way they have gone about it. The young group will grow. They will get better.
“We weren’t good enough in this series, there is no doubt about that. We missed big opportunities to win the series. But if they keep learning and keep growing and keep getting better, it is a group that can play a long time together. That’s the pleasing thing.”
