The Marseille forward Ismaïla Sarr starred as the defending Africa Cup of Nations champions, Senegal, eased into the last 16 with a 3-1 win over Cameroon. Sarr’s deflected strike gave his side a 16th-minute lead and it was he who set up fellow attacker Habib Diallo after the break before Sadio Mané cemented victory at Stade Charles Konan Banny in stoppage time to guarantee his side’s progression from Group C. Cameroon had responded belatedly when Jean-Charles Castelletto powered in a header from Olivier Ntcham’s 83rd-minute cross and Georges-Kévin Nkoudou has guilty of a glaring miss before Mané scored, but Rigobert Song’s men head into Tuesday’s final group fixture against the Gambia with just a single point to their name. Senegal went ahead after the Cameroon defence failed to deal with Pape Sarr’s 16th-minute corner. The ball was fed back in to Sarr after the goalkeeper André Onana had punched it to the edge of the box and he drilled in a low right-footed shot that took a slight deflection off Frank Anguissa and flew into the net. Onana was appearing for the first time at the tournament after his late arrival from his club, Manchester United. Aliou Cissé’s men continued to make the running after the restart, but Olivier Kemen got a sight of goal at the other end, only to loop his 55th-minute header from a deep free-kick high over the bar. Cameroon’s fortunes took a further turn for the worse with 19 minutes remaining when Sarr turned provider with a low cross for Diallo to make it 2-0 from close range. Castelletto gave Song’s side hope with seven minutes remaining and they should have been level when Nkoudou inexplicably headed wide in injury time before Mané wrapped up the points. Earlier, Cape Verde became the first team to qualify for the knockout stages with a 3-0 victory over Mozambique. An extraordinary free-kick from the former Manchester United player Bebé and a double from Ryan Mendes in Abidjan guaranteed that the Blue Sharks will top Group B. Mozambique now lie bottom of the standings with one point before their final group game against Ghana, while Cape Verde meet Egypt on Monday. Cape Verde, fresh from their shock opening victory over Ghana, impressed from the early exchanges. Bebé crashed a dipping 30-yard free-kick against the crossbar, but the former Manchester United forward was not to be denied from an even greater distance. There appeared little danger as Bebé’s stood over a free-kick fully 40 yards out but his swerving shot bamboozled the Mozambique goalkeeper Ernan Siluane, who could only palm the ball into the net. Mendes doubled the Blue Sharks’ advantage after 51 minutes by dispossessing the dawdling Edmilson Dove and firing home from the edge of the box. Mendes scored his second from 25 yards, his thumping drive whistling past Siluane for his 17th international goal. In the day’s final game, Aguibou Camara’s second-half goal fired Guinea to a precious 1-0 victory over the Gambia in Group C.
