The International Cricket Council (ICC) is worried about the Twenty20 format's vulnerability to corrupt practices.

A top official told IANS that it is very tough for its Anti-Corruption and Security Unit (ACSU) to "keep tabs on players in a tournament where national teams are not participating."
"It is becoming tough for ACSU to keep clean a tournament, where national teams are not participating. And now after the spot-fixing incident we are more vigilant. There is still a huge risk to the game of cricket but ACSU has done an excellent job. We have a robust system in place to combat spot-fixing," said the official on the condition of anonymity.

The IPL has been under the scanner after the Board of Control for Cricket in India (BCCI) initially refused ACSU services citing high costs. But the presence of well-known bookie Hamid Qasim Banjo, who shot into limelight in the Hansie Cronje match-fixing scandal that rocked world cricket in 2000 at the Wanderers stadium during the second edition, prompted the BCCI to rope in ACSU.
The official said the popularity of Twenty20 cricket is a worry for the ACSU.
"Twenty20 cricket is very vulnerable to match-fixing since it is very unpredictable. We are still trying to keep it clean and break the betting syndicates," he said.
But still we never know that who and when the match fixing will takes places which can bring bitter in the cricket match. Let’s Hope that there will not be any match fixing & cricket fan will enjoy a lot from IPL Twenty20
