Malik is known to play politics within the team (Abdul Qadir is testament to that)
But Younis' apparent inability to get along with other seniors could also be down to his own uncompromising and dictatorial attitude. He cannot expect to run a cricket team like a cadet company where juniors are supposed to obey you all the time.
Plus as you rightly say Younis cannot really inspire the team if he is himself not scoring any runs. Maybe he is under severe mental stress because of all the politicking that is going on around him and hence cannot concentrate properly on his batting....and let's not forget there are many 'khaleefas' in this team
Malik once lost a match deliberately and admitted to that, I guess it was a local T20 championship.. .what else you could expect from him..
