Quetta Gladiators owner Nadeem Omar on Wednesday said that the Pakistan Cricket Board (PCB) is to mostly blame for the failure of the PSL 2021 bio-secure bubble. "PCB chief Ehsan Mani admitted there is a lack of communication between the franchises and the cricket board," said Omar, while speaking on Geo News show "Score" with Yahya Hussaini. The tournament was postponed earlier this month, leading to disappointment and anger among millions of sports fans across Pakistan. Omar said the PCB was "90% to blame for the failure of the bio-secure bubble".
