According to media reports, the Turkish coach will not be returning to Tehran due to family reasons.
There are also rumors linking him with a potential move to the Saudi club Al Nassr.
Al Nassr has been without a head coach since parting ways with Stefano Pioli.
Possible candidates to replace Kartal include China national team head coach Branko Ivanković and Foolad’s Yahya Golmohammadi.
