LAHORE Former Pakistan cricket captain Mohammad Yousuf should focus only on the Test format of the game, former wicketkeeper Moin Khan said. Yousuf should concentrate only on Test cricket, PakPassion.net quoted Moin, as saying. He felt that Yousuf has had a string of injuries of late, and his old groin injury could shorten his career. Moin was of the view that the rigours of One-day Internationals and Twenty20 cricket could affect the career of the batting stalwart, and that his spot should be filled by Asad Shafiq. Yousuf has a lot of fitness issues and a young player like Asad should get a chance. Asad was playing well in the ODI against South Africa but for some reason he was dropped for Yousuf, he added. The PCB have made a lot of mess. The team should have been finalised 6 months ago, but unfortunately we are still not sure who will be in the squad, Moin said when asked of the Pakistans World Cup chances. He also mirrored the views of ex-Pakistani coach Geoff Lawson by saying, There is lot of instability in the team like the board and if Pakistan does well, it has to be due to individual brilliance.
