Pakistan in Australia 2009

ok dont consider me as Imran Farhat's fan but he was playing domestic cricket before being picked. Also YOUNUS KHAN OPTED out of the team because he was out of form, FAIR ENOUGH. Now tell me what has he done to get IN FORM? Why should he be PICKED? What has changed since he LAST PLAYED? I'd assume he even got MORE RUSTED by not playing any form of cricket.
