Rajasthan skipper Shane Warne has suggested that the IPL tournament should be shortened to a month in the coming years.

"The IPL should be played for four weeks in April and the final on May 1. The ICC should make sure there is no international cricket during the period and all the international players should be available for the IPL," he said in Mumbai a day ahead of the finals.

The current Indian Premier League Twenty20 tournament is spread over 44 days between April 18 to June 1.

Asked about the stupendous success of his team in the tournament and the mantra behind it, Warne said it all came from playing two practice matches.

"When we reached here we wanted a background of all the players through the local coaches which unfortunately we didn't get. We played two practice games straight away and watched every player in detail as to how they approached the game, their shot making, running between the wickets, fitness and other aspects," he said.

He also credited Rajasthan's performance coach Jeremy Snape and director of coach Darren Berry of doing a great job with the players and giving him an idea of what each one of them was capable of.

Warne heaped praises on his young team and said: ""The young guys are not scared of reputations. These young guys are making me feel young.

"Ravindra Jadeja is a rockstar. He will be the next superstar for India. Asnodkar is a terrific shot maker. Yusuf Pathan is finally fulfilling his potential and he has been rewarded with a place in the Indian ODI side. It makes me proud as the captain of the Royals," added the 38-year-old Aussie.

Warne also said he is keen to open a spin academy in India on the lines of the MRF Pace Academy that grooms young fast bowlers.

"I am impressed with Dennis Lillee and the MRF Pace Academy. They have done a good job and helped develop fast bowlers in India. I am looking to set up same sort of spin academy to help young spinners. I am impressed with the likes of Amit Mishra and Piyush Chawla and hope to help them in the future," he added.
