Cameroon have crashed out of the 2017 FIFA Confederations Cup following a 3-1 defeat to Germany at the Fisht Olympic Stadium in Sochi, Russia on Sunday evening.
As a result, the FIFA World Cup holders advance as Group B winners with Chile ending as runners-up following their 1-1 draw with Australia.
Die Mannschaft will face Mexico in the semifinals with Portugal and La Roja to lock horns in Kazan.
The Indomitable Lions played the final 25 minutes with 10-men following the controversial sending off of Ernest Mabouka. The Germans took fool advantage as they cruised into the knockout stages.
Victory sealed a 100th win in 150th games in charge for German coach Joachim Louw.
Hugo Broos named the same starting 11 for the third game in succession following an injury to Georges Mandjeck in the warm up - Arnaud Djoum subsequently retook his place on the pitch.
Needing nothing but a win, the Indomitable Lions were quick out of the blocks and made a positive start; the Africans just lacking in the final third.
Germany would then create two good chances in quick succession with Emre Can seeing his curling effort inches wide before Joshua Kimmich headed wide with the goal at his mercy.
The African champions ended the half on top with André-Frank Zambo Anguissa forcing Marc-Andre ter Stegen into a good save a minute before the break.
It would be the Germans, though, to open the scoring three minutes after the interval. Hoffenheim midfielder Kerem Demirbay charging onto a nifty pass from Julian Draxler before powering an unstoppable shot into the roof of the net.
Fabrice Ondoa was called into action once more in the 54th minute, with the Cameroon number one pulling off two world class saves to deny Louw's troops.
Mabouka would receive his marching orders in the 65th minute following what was a contentious decision by the referee. Following advise from the Video Assistant Referee (VAR) the official adjudged the defender's challenge on Can to have been of a dangerous nature.
Having initially sent off the wrong player, the referee luckily gathered himself to spare his blushes - to an extent.
Germany would take full advantage as RB Leipzig forward Timo Werner doubled their lead a minute later. A superb diving header leaving Ondoa with little chance.
There would be a glimmer of hope for Cameroon in the 78th minute as Vincent Aboubakar nodded home from an acute angle. Ter Stegen guilty of some questionable goalkeeping.
The goal would prove a mere consolation as Werner completed his brace with a superb finish three minutes later. Germany on course as Cameroon return home.
