Al-Ahli host their counterparts Al-Nassr on 20 November, at the Al-Inmaa Stadium in Jeddah, in a rescheduled match from the ninth round of the Roshn League.
The Saudi newspaper "Al-Riyadiyah" report that Al-Ahli's management are currently hunting for a suitable formula to end their contractual relationship with Pocetic before the anticipated Clasico against traditional rivals Al-Nassr.
For now, though, the signs point to the Dutch coach taking charge in the Clasico against Al-Nassr, with the departure procedures yet to be finalised.
Al-Ahli fans had launched a fierce campaign across social media, under the banner (Pocetic's departure is our demand), to force the Dutchman out of his job in the dugout, furious at the team's recent results.
That campaign only intensified after the heavy 6-1 beating "Al-Raqi" took against Al-Shabab in the twelfth round of the Saudi Roshn League.
