Ahmed Hassan 'Koka' scored a sensational hat-trick to inspire Rio Ave's 5-1 Portuguese league win over Estoril. The Egypt striker hit the first three goals of the game in the space of an hour, before Pedro Moreira added a brace to complete the rout. It is the first hat-trick for the 21-year-old Koka, who is now joint-top scorer of the Liga Portuguesa after two weeks as Rio Ave lead the table with six points. Koka has just been called up by Egypt for the 2015 Africa Cup of Nations qualifiers against Senegal and Tunisia next month. VIDEOS
