Liverpool forward Sadio Mane found the net as Senegal beat Zimbabwe to become the first team to reach the 2017 Africa Cup of Nations quarter-finals.
Mane scored the opener from close range in the ninth minute from Lazio forward Keita Balde Diao’s low cross.
Henri Saivet, on loan at St Etienne from Newcastle, then fired home a brilliant 20 yard free-kick four minutes later.
Mane also had a shot cleared off the line by Costa Nhamoinesu.
Stoke’s Mame Biram Diouf should have made it 3-0 to Senegal’s advantage, but rifled his left-foot shot over the crossbar.
Khama Billiat wasted a good chance for Zimbabwe just before half-time when he hit a weak shot at Abdoulaye Diallo. The keeper also produced a great save to keep out Nyasha Mushekwi’s drive.
The Lions of Teranga have a maximum six points from two games in Group B.
Tunisia are second-placed with three points and both Algeria and Zimbabwe have one point each.
