The 2011 ODI world champions had a dream run in the just-concluded edition of the mega event till the semi-final where they stumbled against Australia.
The former India left-arm spinner, who played in two World Cups (1992 and 1996), said there's nothing wrong in the system but there's a strong need to organise 'A' tours to make a pool of reserve players.
"The amount of cricket the Indians play is a lot more than others, so there's always an issue of burnout. We should have a back-up of at least five-six pacers and three-four spinners ready all the time.
He added, "We have a long domestic season with Ranji Trophy being the benchmark of national team selection. There's nothing wrong in that but it would always be nice to have three-four A tours in between. I'm sure our players would benefit a lot. If you see, in 2007-08 we had a lot of India A tours," he said.

The former India left-arm spinner felt that it was tough for the Saurashtra allrounder to return and start performing straightaway.
Citing the example of Jadeja, Raju reiterated the need to have a back-up plan ready at all time.
"He was a match winner before playing the World Cup but his form dipped. It was disappointing to see that. But it does happen when you make a comeback. It's difficult to adjust to the top level," the 45-year-old said.
