Zamalek full-back Omar Rabie Yassine requested to make his contract with the Cairo club null and void after getting fed up with his non-participation. Yassine, who was landed by the White Knights in January, hasn't made his Zamalek debut thus far, which prompted him to consider leaving the troubled outfit. "I want to cancel my contract with Zamalek," former Lierse man told FilGoal.com. "I was constantly shunned over the past weeks, so I asked assistant coach Mahmoud Saad about the reason why I haven't been named for a single match until now." Zamalek were having several problems at the left-back position recently, nevertheless, Swiss boss Michel Decastel didn't pick Yassine, who can play as a left winger, for any of Zamalek's league reverse fixtures. Decastel usually opts to field either Sabri Rahil or Alaa Ali instead. No Chance Yassine believes he has absolutely no chance of establishing himself with Zamalek. "Saad told me that I was only signed out of sheer stubbornness, and these words made me more determined to exit," the 21-year-old explained. "I don't think Zamalek would mind letting me go. I penned a five-year contract for EGP 620,000 per season, and so far I haven't got a cent." In the past January transfer window, Petrojet made serious overtures towards Yassine, but he eventually joined Zamalek.
