"The path should be that knowing well you have got 12 months to go for the T20 World Cup and you have about 18-20 months to go for the World Test Championship," Shastri told the Gulf News on his return from the tour of Caribbean.

"Getting youth in during that transition period by keeping an eye on the youth is important so that they can mix with the experience and give us a really solid side."

At the same time, Shastri said that with points at stake, World Test Championship is a serious business.

"We are playing at home (against South Africa) and it is the World Test Championship - so now there is even more reason on why you have to play the way you should. There are now points to be accumulated.

"We are the No. 1 team in the world and we have been for the last three years, so there is pride at stake as well. So we want to keep that consistency going and ensuring that we are placed nicely in the table for when the time comes from them to decide who plays in the final."

Shastri was pleased as punch that his team was able to maintain an unbeaten record in the West Indies, the first team to do so in the assortment of island nation.

"To beat the West Indies in West Indies across all three formats, especially the limited over formats and Test matches, I think this must be unprecedented. A team going to the Caribbean and not losing a single game, I don't think it has happened in the past and it will not happen that easily in the near future," he added.
