Thomas Muller scored the winner as Germany came from behind to defeat Romania 2-1 in Hamburg and move six points clear at the top of World Cup qualifying Group J.
The hosts fell behind to Ianis Hagi's wonderful individual effort after just nine minutes at the Volksparkstadion.
But Serge Gnabry's fifth goal of the qualifying campaign levelled matters, with Germany leaving it late to complete the turnaround.
Hansi Flick's side did so nine minutes from time, substitute Muller marking his 107th international cap by turning home a corner at the far post.
