LAHORE - Shoaib Malik and many other players including Shoaib Akhtar and Shahid Khan Afridi would face tough times if they fail to impress selectors. Malik has been put under scanner to prove his worth as the skipper before India arrived for its tour as PCB Chairman Ijaz Butt said captaincy would be up for review after the all-rounder's term expired at the year end. "Anyone in the Pakistan team holding any position has to be deserving of his place in the team," Butt was quoted as saying by a website. He added that it was premature to say if Malik would retain his captaincy or the governing body of the board might decide to go for a change. "All I can say the captaincy would be up for review after December 31 and before the Indian tour of Pakistan from early January," Butt said. The latest statement from the PCB Chief means that Malik is not guaranteed the captaincy for the India series and more importantly Malik would be under pressure to produce good results in the One-day series against the West Indies in Abu Dhabi from November 12. Malik's captaincy has come under a lot of criticism from some former players more recently by his former skippers, Wasim Akram and Inzamam-ul-Haq who felt the Board would be better off appointing a more senior player as the captain to get consistent results from the team. Butt has already made it clear that the Australian coach of the national team, Geoff Lawson would not be retained once his contract expires in mid of next year. Meanwhile, the coming time not only seems difficult for Malik and Lawson but several other players would also come under close watch. Interim chief selector, Saleem Jaffer, said the form and fitness of Shoaib Akhtar, Shahid Afridi, Umer Gul and Sohail Tanvir would be closely watched during the Pentangular Cup which begins from October 25 at different venues in the country. Jaffer, who was recently appointed chairman of interim selection committee, said the four players had appeared in the Twenty20 tournament in Toronto but the event was not enough to properly assess their form and fitness. "The selectors don't think Twenty20 cricket is the right format to judge a player's output and fitness. In Toronto, we noticed some issues with these players. We are still not sure if Shoaib is 100 per cent match-fit, Afridi is struggling with his batting form, Umer Gul has come back after an injury and Tanvir was not impressive in Toronto," Jaffer said. Jaffer, himself a former Test pacer, said after meeting with the new PCB chairman Ijaz Butt, the selectors were assured they can act independently and should not compromise on discipline or fitness with any player. "So the Pentangular tournament's opening matches would be a good platform for these players to convince everyone about their form and fitness and retain their places in the national team for the upcoming one-day series against the West Indies in Abu Dhabi," Jaffer added. Shoaib Akhtar returned to international cricket after a nearly ten-month lay-off due to fitness and disciplinary issues and he struggled in the Toronto event final conceding 40 runs in three overs against Sri Lanka. The Pentangular Cup will feature all the top players in the country representing their provincial sides.
