Cameroon’s Confederations Cup campaign is over after a 3-1 defeat by Germany in their final Group B game on Sunday.

Timo Werner netted twice as Germany set up a Confederations Cup semi-final against Mexico with a 3-1 win on Sunday against 10-man Cameroon, while Vincent Aboubakar grabbed a consolation goal for them.

The Indomitable Lions also had Ernest Mabouka sent off after confusion involving the Video Assistant Referee.

Germany midfielder Kerem Demirbay opened the scoring just after the break before Werner struck either side of Vincent Aboubakar’s consolation effort for Cameroon on 78 minutes.

But the video assistant referee system was again thrust into the spotlight when Cameroon defender Ernest Mabouka was sent off just past the hour for a dangerous tackle on Liverpool’s Emre Can.

Colombian referee Wilmar Roldan initially sent off Sebastien Siani by mistake, before the decision was rectified and Mabouka was dismissed instead.

“I didn’t understand it and I still don’t understand it now,” fumed Cameroon’s Belgian coach Hugo Broos.

“I think this is something for the referee, he and he alone can explain what happened.”

The victory in Sochi meant Germany finished top of Group B ahead of Chile, who drew 1-1 with Australia in Moscow.

The Germans face Group A runners-up Mexico in Sochi next Thursday in their semi-final, while Chile will face Portugal on Wednesday in Kazan.
