A thunderous strike by substitute Adil Boulbina deep in extra time settled a tense encounter as Algeria beat the Democratic Republic of Congo 1-0 in their Africa Cup of Nations (AFCON) last-16 tie. The game at the Moulay El Hassan Stadium in Rabat, Morocco on Tuesday was edging towards a penalty shootout when Boulbina, a forward who plays club football in Qatar, was released on the left in the 119th minute and advanced into the area before unleashing a vicious strike into the net.
