Zamalek defender Mohamed Sedik has signed a four-year deal with his team's arch-rivals Ahli, the Egyptian champions said on Monday. Sedik signed for Ahli on Sunday night, an Ahli official, who spoke on condition of anonymity told FilGoal.com. The Ahli official did not disclose the financial details of the move but stated that Sedik will be with Ahli until 2010. "Sedik is a great addition to the team because he can play in various positions in defense," the Ahli official said. The 27-year-old defender is the second Zamalek player to sign for Ahli this week after colleague Tarek Al-Saied. Both players will be presented to the media after the conclusion of the Egyptian league on Monday.
