Holders Senegal sailed into the knockout stages of the Africa Cup of Nations with a 100 per cent record after beating Guinea 2-0 in Yamoussoukro.
Abdoulaye Seck headed the opening goal early in the second half and Iliman Ndiaye added a late second for the in-form favourites.
Defeat means Guinea, who went into the game knowing they would at least qualify as one of the best third-placed teams, must face Group A winners Equatorial Guinea.
A dismal first period yielded no shots on target, although Senegal did come close when an effort from Nampalys Mendy was deflected just over the bar.
After a fractious end to the first period which saw players from both sides having to be separated, Sadio Mane missed a golden chance shortly after the break.
The former Liverpool man rounded Guinea keeper Ibrahim Kone but failed to keep his shot on target and fired wide.
Seck rose unmarked to head home the opener from Krepin Diatta’s pinpoint free-kick and the goal clearly settled the hosts, who assumed full control.
Ndiaye’s excellent finish wrapped up victory on the stroke of full-time, but there was still time for Guinea to at least register a shot on target as Morgan Guilavogui’s volley tested Edouard Mendy in the Senegal goal.
