Germany defeated Cameroon 3-1 on Sunday to finish top of Group B at the 2017 FIFA Confederations Cup at the Fisht Stadium in Sochi, Russia in front of 30,230 fans.
After a goalless first half, highlighted by a superb save from Marc-Andre Ter Stegen, Germany eventually found the breakthrough thanks to Kerem Demirbay.
He scored his first goal for Germany with a thunderbolt finish 25 yards from goal after captain Julian Draxler played him through with a neat flick.
Cameroon were reduced to 10 men in the 64th minute when, after a video assistant referee review, Ernest Mabouka was sent off for a late challenge on Emre Can.
Werner then gave Germany a two-goal cushion with a diving header, his first goal at senior international level, from Joshua Kimmich’s cross on the right wing.
Vincent Aboubakar found the net with a glancing header with 10 minutes remaining, but Werner restored Germany’s two-goal lead to ensure their first-place position in the group.
Werner also became the first German to score two goals in a single Confederations Cup match with his close-range, accurate finish.
The victory means that Joachim Low’s side will stay in Sochi for their semi-final fixture against Mexico on Thursday.
