Ahmed Hassan ‘Koka' scored his fourth Portuguese league goal of the season to salvage a 1-1 draw for Rio Ave at Nacional. The 20-year-old Egyptian scored a 71st minute penalty to cancel out Claudemir's strike for Nacional to end Rio Ave's two-match losing run. Koka's strike came eight minutes after Egyptian defender Ali Ghazal came on for Nacional, making his third appearance since joining from Wadi Degla last year. Rio Ave remain winless for the fourth game in a row but keep their place in fifth, while Nacional are ninth of the Liga Sagres table.
