There is talk about Test captain Misbah-ul-Haq having an argument with his deputy Muhammad Hafeez during the third Test, which the team lost by an innigs and 18 runs today.
"The argument was the result of Hafeez's insistence on having the ball changed during South Africa's first innings in the first session on the second day after which the South Africans added more valuable runs to their total.
The source said they were even question marks over whether fast bowler Umar Gul, the most experienced bowler in the side, could have played the third Test.
"There is a big question mark over how serious was Gul's illness that kept him out of the Test or whether he himself had lost the will to play the match after struggling in the first two matches," the source said
"Certainly now questions need to be asked over the role/influence of some seniors in the dressing room after the way the team crumbled in the matches," the source said.
