Ruthless Germany brush aside Northern Ireland to book World Cup spot
Germany will be in Russia next summer to defend their World Cup crown having sealed their qualification by inflicting a first competitive home defeat on Northern Ireland in four years.
Michael O'Neill's men last lost a qualifier in Belfast to Portugal in September 2013 when Cristiano Ronaldo scored a hat-trick and, while they were undone by arguably the world's best player that night, they were beaten 3-1 here by perhaps the planet's finest international team.
Sebastian Rudy's sweetly-struck effort from range 83 seconds in ended Michael McGovern's 10-hour run without conceding an international goal, and it was game over when Sandro Wagner rolled Gareth McAuley and fired home after 21 minutes.
The tremendous Joshua Kimmich fizzed in a back-post volley four minutes from time before Josh Magennis claimed a consolation for the hosts in stoppage-time.
It continued the Germans' phenomenal record of having never lost an away World Cup qualifier, while maintaining their 100 per record in Group C, with Northern Ireland's focus on second place ever since they were drawn against Joachim Low's side.
The runners-up berth has already been sewn up ahead of their final qualifier in Norway on Sunday, and they could be assured of a play-off place before that if results on Saturday night go their way.
Crucially for O'Neill, neither their goal difference or perilous disciplinary situation were impacted too much - and they remain very much on course for a two-legged tie in November that will determine if they will join Germany in Russia.
After being given the run-around by the Germans three times over the past 16 months, they will hope the draw is kind.
McGovern's long run without conceding dated back a year, yet it was ended inside two minutes, and in some fashion.
As was the case with so many German attacks in the first period, it originated down the right. Leon Goretzka's cross was volleyed out by Lee Hodson to Kimmich and he teed up his Bayern team-mate Rudy to unleash a 30-yard bullet into the top corner.
The presence of Kimmich effectively as a right-sided forward was nothing new to Northern Ireland - they witnessed it at Euro 2016 - but Chris Brunt at left-back simply could not cope.
McGovern clawed out one Wagner effort and another from a Kimmich cross was nodded on to a post. However, the Germans' bustling focal point did not have to wait long to double the visitors' lead.
Thomas Muller rolled the pass into the Hoffenheim forward and he took a touch to open his body up and turn away from McAuley before ruthlessly rifling a left-footed attempt beyond McGovern.
It could have got worse, Rudy, Kimmich and Wagner nearly linking up for a delicious third, but it should also have been a better outcome at the break.
When Magennis' right-wing cross came all the way through to Corry Evans at the back post, he looked like a man who had not scored in seven years. A hesitant first touch was followed by an indecisive finish that Marc-Andre ter Stegen kept out.
O'Neill recognised the need to try and nullify Kimmich's threat and brought on Stuart Dallas at the start of the second period for Hodson, switching to a back four in the process, and the home side were much improved after the break, even if they were indebted to McGovern's fine save to deny Muller.
Another opportunity to make it 2-1 was passed up, substitute Conor Washington side-stepping Jerome Boateng with ease only to lash his attempt on to the frame of the goal.
Kimmich's quieter second half did not prevent him from getting in on the act as his fine volley beat McGovern at his near post after Marvin Plattenhardt's delivery was headed into the sky by Jonny Evans.
Amazingly, the Green and White Army were still singing at full-time thanks to Magennis heading home from a Brunt corner that was directed to him by McAuley.
A historic win proved beyond Northern Ireland, but the chance to make history by reaching back-to-back finals is still on regardless.
