Joachim Low's side opened its Group J campaign with a 3-0 win at home to Iceland on Friday and it put in another dominant display at the National Arena to swat aside Mirel Radoi's men.  

Die Mannschaft had 18 shots to the host's nine, but they were limited to just a solitary goal, the impressive Gnabry securing maximum points with a close-range finish after 16 minutes. 

The result means Germany are top of Group J on six points, ahead of Armenia on goal difference, and three points clear of Romania and North Macedonia.

Kai Havertz and Valentin Mihaila exchanged chances in the early stages, before Gnabry put Germany ahead.

Havertz surged into the penalty area and slid an inviting ball across goal, which the Bayern Munich forward easily slotted home from eight yards.

Joshua Kimmich then thundered against the crossbar from distance, with Florin Nita keeping out Gnabry's follow-up effort as Germany ultimately failed to add to their advantage.

Nita pawed away a fierce Leon Goretzka drive shortly after the restart, while the Romania goalkeeper got down well to deny Gnabry a superb solo goal before the hour mark. 

Leroy Sane and Timo Werner missed presentable opportunities inside the final half-hour, while George Puscas tested Manuel Neuer late on as Germany secured another three points on what is shaping up to be a smooth progression to Qatar 2022.
