Egypt starlet Ahmed Hassan ‘Koka' registered his maiden Portuguese league goal for Rio Ave but his side lost 3-1 at home to Vitoria Guimaraes. Teenager Koka, who scored twice in the league cup before, came off the bench in the 63rd minute when the score was 1-0 to Vitoria, only to find the net two minutes later with a clinical finish. The visitors restored their lead with a penalty as Koka almost equalized three minutes from time but his header went wide, shortly before Amidio Balde scored the third for Vitoria. Despite the defeat, Rio Ave remain in the top five with 21 points from 15 games so far. Koka's goal Koka's chance
