LAHORE - The Pakistan Cricket Board (PCB) and Cricket Australia (CA) have yet to sign a memorandum of understanding (MOU) for the upcoming ODI series that gets underway from April 22 in Dubai and Abu Dhabi. According to reports, officials of both the boards are presently in Dubai and Abu Dhabi to oversee arrangements and preparations for the upcoming series that will include five ODIs and a Twenty20 match till May 7. "The officials are holding meetings with the Emirates cricket board and the broadcasters of the series to discuss arrangements for the series with special emphasis on security," a board official said. He said a security consultant from Australia was also involved in the discussions and the Australians has already raised some issues with the stadium at the Dubai sports city which is to stage two ODIs and a Twenty20 match. "The Australians want some assurances about the stadium," the official said pointing out that the Dubai sports city ground would be ready by the end of March. "It is a new venue so obviously the venue has to be tested out before hosting the international matches," he added. He said the MoU would be signed soon once all issues are sorted out. Reports say the Australians are laying a lot of emphasis on security arrangements for the series and have asked for specific assurances from the local organisers. "After the incident with the Sri Lankan team in Lahore the Australians are not willing to take a chance at all with the security arrangements," one report said. Pakistan agreed to play the series at neutral venues after Australia refused to send its team to the troubled nation because of security concerns for its players. The two teams have played a Test series in 2002 at Colombo and Sharjah after the Australians refused to send its team to Pakistan following the 9/11 incident.
