Miandad was quoted as saying in a Pakistan daily-The News that the Twenty20 format was a circus and does not augur well for the betterment of Pakistan cricket.
"This is not cricket. It is a circus and if we lay too much stress on it at the domestic level it is going to have detrimental effect on our future generation of players," The News quoted.
Miandad highlighted the fact that Pakistan was struggling to churn out quality players and the new format would do no good for the cricket in the country.
"They introduced this form of cricket in England because of financial requirements. I don't think the Pakistan board has any financial problems that it should need to introduce Twenty20 type of tournaments in our domestic calender."
He asserted that the Twenty20 cricket would neither improve the player's techniques nor prepare them for Test or One-day International cricket.
"It could end up destroying the confidence of the bowlers who are always going to be at the receiving end in this format and convert batsmen into slam bang cricketers. Pakistan is already short of quality batsmen who can graduate to the international level and adjust accordingly because there has been a dearth of three-day and four-day cricket at the inter-school and club levels. In the domestic tournaments the quality needs to improve in the regional tournaments," Miandad added.
