The goal itself was significant -- it ensured that Cairo's mighty Al-Ahly team would beat South Africa's Orlando Pirates for its eighth champions league title. But in Egypt, it was Abdel Zaher's celebration that later stole the limelight. For his four-fingered salute has over the past three months become a potent and divisive sign of opposition to the overthrow of Egypt's former president, Mohamed Morsi. It invokes August's bloody demolition of an encampment of Morsi's Islamist supporters outside a mosque called Rabaa al-Adawiya. (Rabaa means 'fourth' in Arabic.)
