The Chairman of the Pakistan Cricket Board (PCB) Shaharyar Khan confirmed that Azhar had been offered the job, which would also include duties of a bowling coach.
"Azhar has agreed to take up the assignment but will confirm once he has settled some contractual obligations with his county in England," Khan said.
He said Azhar's appointment has been made after consultations with new head coach Mickey Arthur.
"Mickey Arthur had specifically asked us to appoint a Pakistani assistant coach with him as this would make it easier for him to settle down quickly in the team and also communicate and understand the players psyche better," Khan said.

According to a reliable source in the PCB, Arthur had been keen to have former Test leg-spinner Mushtaq Ahmed as his assistant coach but the PCB said the latter couldn't be released from his duties at the National Cricket Academy since a new Director of academies Mudassar Nazar was due to take over from June 15th.
Azhar was also appointed bowling coach on a special short-term assignment for the World T20 in India, where Pakistan faltered badly and this led to changes in the team management with head coach Waqar Younis stepping down and the national selection committee being disbanded.
