Shastri said that India have got the right balance in the team and most of the big players are in form at the right time ahead of the ICC event.
"We have got into a good habit of winning games. You might get the odd hiccup on the way. But it's important to maintain a level of consistency and treat every game as an important game. Every game is important from here on," he told a news conference.

Key players like Ajinkya Rahane and Harbhajan Singh did not get a chance to play but Shastri said that the problem of plenty was a good headache .
Not long ago, the bowlers faced severe criticism from several quarters for the team's woes but Shastri felt the bowling unit has made a turnaround. He gave credit to bowling coach Bharat Arun for the new-found success of the likes of Jasprit Bumrah and Hardik Pandya, along with veteran Ashish Nehra.
"Earlier, the bowling look jittery because we had some injuries. In the South African series, we lost an inform Ashwin early... We have not had Shami since the World Cup. We had to look for some new players for a big bench strength."
Shastri also spoke about the in-form Virat Kohli and said the number three batsman has a hunger to perform on a big stage.
"Every time he bats you can all see it's passion written all over. You can see his body language, he just loves the big stage. He wants to compete against the best in the world," said the Team Director.
"As we saw against Pakistan (in Asia Cup), for him to bat in that fashion after Aamir's spell, it was a world class innings. He's a kind of player who's hungry. He wants to score big once he gets going."
He also slammed the critics for their non-stop criticism of captain Mahendra Singh Dhoni, saying that he (Dhoni) has nothing left to prove and a champion like him should not be treated like that.
"I've said long back that he (Dhoni) is the best. What else he's left to be achieved... Even you must be tired of watching him winning but still there will be two-three who will want him to retire. This thing is normal in our country. You go after your champions and tell them to go, it's enough," he said.
