Germany made it two wins from two in World Cup qualifying as Serge Gnabry's first-half goal sealed a 1-0 win over Romania on Sunday. 

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

Die Mannschaft had 18 shots to the hosts' 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. 

Germany head coach Joachim Low admits he is not completely satisfied with his side with just three months to go until the delayed European Championship finals.

Die Mannschaft cruised to a 3-0 win over Iceland in their opening World Cup 2022 qualifier on Thursday through goals from Leon Goretzka, Kai Havertz and Ilkay Gundogan.

It was a welcome win for Low's men, coming on the back of a 6-0 hammering against Spain in their final match of a poor 2020 that saw them win only three of their eight games.

Germany had 81.5 per cent of the ball, attempted 1,053 passes and had 15 shots compared to Iceland's eight, but Low feels there is plenty of room for improvement.

"I wasn't exactly full of praise for the whole game," he said at a news conference on Saturday previewing the trip to Romania.

"We could have done better in the second half in particular. If we look to the Euros, we have to improve in a few areas. 

"It was a good start and we had a lot of well implemented play. But I'm not yet completely satisfied."

Without the influential Toni Kroos, who withdrew from the squad with a knock, Germany's midfield three of Gundogan, Goretzka and Joshua Kimmich impressed against Iceland.

Jamal Musiala made his debut as a second-half substitute in Duisburg, while Borussia Monchengladbach's highly-rated Florian Neuhaus was also introduced for his fourth cap.

But Low insists Kroos, who remains a regular for Real Madrid, is still integral to his plans.

"The midfield set the tone against Iceland, everyone in their own way. I'm happy about that. But Kroos is a player with immense value to us," said Low, who will end his 15-year tenure after Euro 2020.

"Our strength at major tournaments has been players coming off the bench. We have good players in midfield - any team who wants to achieve something needs that."

Germany's win over Iceland was their 17th in a row in World Cup qualifying, setting a new record and placing them top of Group J ahead of Sunday's trip to Romania.

Niklas Sule has been ruled out of both that match and Wednesday's visit of North Macedonia, while Robin Gosens is also out and Goretzka and Leroy Sane are carrying knocks.

Low does not intend to make many changes ​for the showdown at the National Arena as Germany seek back-to-back competitive wins for the first time since November 2019.

"I'm going to wait until tomorrow to see how things develop with Leon," Low said. "He is the first option in midfield and I hope he can play from the start.

"If he doesn't then it is possible to let Musiala play, or move Serge Gnabry deeper and bring in Timo Werner. Our usual defensive line will start."

Romania kicked off their qualifying campaign with a 3-2 home win against North Macedonia to make it four games without defeat, scoring 12 goals across those fixtures.

And Low expects to face an attack-minded side in Bucharest.

"They have great strengths on the attack and act much more aggressively than Iceland," he said. "We will face completely different challenges.

"I've seen Romania one time or another and we have a lot of information on them. 

"They have technically well-trained players who want the ball. They don't want to defend so much, but they want to play forward. I think Romania's central midfield is very good."

Real Madrid midfielder Toni Kroos has withdrawn from the Germany squad for their upcoming fixtures because of an adductor injury.

The 31-year-old linked up with his national side on Monday for the World Cup qualifiers with Iceland, Romania and North Macedonia.

However, Germany confirmed on Tuesday that Kroos has returned to Madrid as a precautionary measure and will play no part in any of their games over the next eight days.

"Our medical department has examined and treated Toni intensively," said head coach Joachim Low, who will step down from his position at the end of the rescheduled Euro 2020 tournament.

"He would have liked to stay with us, and I am reluctant to be without him. But with a view to the Euros, we decided that the full recovery from this injury must be a priority."

Kroos earned his 100th cap for Germany in October's 3-3 draw with Switzerland and has featured 35 times in all competitions for Madrid this season.

He previously missed two games earlier this season with a gluteal injury, seeing him play no part in the league wins over Real Valladolid and Levante.

Germany are also without Niklas Sule and Robin Gosens for Thursday's clash with Iceland in Duisburg, the pair unavailable with thigh and muscular problems respectively.

The build-up to the match has been dominated by talk of who will succeed Low as the next Germany head coach, but Manuel Neuer insists it will be business as usual on the field.

"We had a short team meeting and are concentrating on our tasks," he said. "We have to be well prepared for the European Championship and will use every game to do that.

"We cannot make any more mistakes. We have a strong group, against some strong opponents, so every game is a final from the start.

"Of course now we want to crown this era with a success. The coach deserves that to end with a success after the successful years.

"He is is very motivated and ambitious. It's not that he thinks he's going to retire. He's enthusiastic. He wants to quit as national coach as successfully as possible."

Under-21s boss Stefan Kuntz is among the frontrunners to replace Low, who has been at the helm since 2006 and guided his country to World Cup success in 2014.

Ralf Rangnick and Hansi Flick, who manages Neuer at club level with Bayern, are also in the running, while Jurgen Klopp and Julian Nagelsmann have distanced themselves.

Asked about the candidates for one of the top jobs in football, Neuer said: "A national coach must have experience and must have done one or the other in German football. 

"He should know the Bundesliga. It's not about what we think, but about the goals that we have in front of us."
