"I am not bothered about the scoreline because of the way they have played. I have seen teams in the past, where we have gone down, buckled under pressure and there has been no competition whatsoever. Here they have taken the attack to the opposition," Shastri told 'Star Sports'.
"The average age of this side is 26. Again, no excuse. But give this side, like I said, 12 months and you watch, they will be a bullet side. They will be ready to play anywhere, he added.
"Areas are there they have to be addressed. Like better batting from the tail. How do you cope with pressure? How do you don't have batting collapses? How do you eradicate your mistakes and don't keep repeating them. Those have to be addressed," the former Indian captain said.
"But this is the first draw at MCG in the last 10 years. And when you have a scoreboard total of 530 and the batting that I saw on Day 3, I think I have not seen for a long long time. I think whole of Australia stood up and acknowledged the fact that two young turks took the attack to the opposition.
The 52-year-old Shastri, who played 80 Tests and 150 ODIs during his 11-year-old career, opined that the team does miss a Sourav Ganguly-like all-rounder.
"What we miss overseas is a batsman in the top six who can bowl. Someone like Sourav. When Sourav played he could bowl 10 or 15 overs. A medium-pace bowling all-rounder overseas. If you have that, it will be a big help. And that will be the endeavour, he said.
