Now the even harder part begins: having qualified for the FIFA World Cup Russia 2018, Germany coach Joachim Löw must pick a squad for the tournament. With no shortage of experts hailing the country's wells of talent, we took it upon ourselves to see just how deep they run, drawing up no fewer than FOUR world-class starting line-ups.
That's right - FOUR! Allow bundesliga.com to present Germany's incredible strength in depth...
Boasting seven World Cup winners and a youthful injection in the form of Bayern Munich’s Joshua Kimmich, this line-up is a combination of the players Löw prefers to utilise and those who would feature were everyone fully fit.
Kimmich’s vision, energy and reading of the game make him a ready-made replacement for former team-mate Philipp Lahm - Löw recently called Kimmich "world class" - while Cologne’s Jonas Hector has cemented his spot as first-choice left-back since making his debut in November 2014.
The spine of the team is built around the 2014 World Cup winners: the Bayern core of captain Manuel Neuer, Mats Hummels, Jerome Boateng comprise a formidable defensive trio, while Toni Kroos and Sami Khedira - both starters in last season's Champions League final with Real Madrid and Juventus respectively - dovetail naturally in midfield. Thomas Müller is as Thomas Müller does, while Mesut Özil's quality and experience guarantee him a spot.
Timo Werner’s remarkable recent form for RB Leipzig makes him the first-choice out-and-out striker, although should either Mario Gomez or Sandro Wagner continue to impress during the Bundesliga season, then they will put pressure on Werner’s place.

It goes without saying that Löw has alternatives in the attacking midfield positions at the ready should he prefer to shift Müller into the lone striker role or should Marco Reus' injury troubles continue.
Although it only features one World Cup winner from 2014 (Julian Draxler), this iteration is perhaps representative of some of the new wave of talent, as well as some of those on the comeback trail from injury, such as Ilkay Gündogan.
Leon Goretzka’s fine run of form for Schalke and performances at the Confederations Cup mean he is pushing hard for a spot in the first-choice midfield. Behind him, Sebastian Rudy is one of Löw’s reliable options in midfield: the Bayern man was impressive in qualifying, not least in scoring a stunning goal against Northern Ireland.
Captain of the Confederations Cup-winning unit, Draxler is also in contention for the first-choice side, given Reus' well-documented injury troubles, while Gomez, although currently injured, provides nous and experience up top - as well as a guarantee of goals (31 in 71 caps).
Marvin Plattenhardt looks to be at the front of the left-back queue when Hector is unavailable; Hertha Berlin’s free-kick specialist is as impressive going forward as he is solid in defence. Elsewhere, given that Niklas Süle continues to impress in Bayern colours, it’s hard to overlook his claims to be the next cab off the centre-back rank behind Hummels and Boateng.
Marc-Andre ter Stegen is already pencilled in as Manuel Neuer's No2 - will there be a better back-up goalkeeper in Russia? - while Bayer Leverkusen's Benjamin Henrichs is perhaps most in danger of slipping out of this team after a slow start to the 2017/18 Bundesliga campaign.
If you want proof of Germany's current strength in depth, then how about this: our third-choice line-up contains three World Cup winners from 2014 (Mario Götze, Shkodran Mustafi and Benedikt Höwedes).
Bernd Leno’s impressive displays so far this term for Bayer Leverkusen look to have the keeper ahead of Kevin Trapp - who has lost his place at Paris Saint-Germain - in the running to be third choice at the World Cup.
In front of Leno, Jeremy Toljan’s move to Borussia Dortmund has catapulted him up the full-back queue, while Jonathan Tah adds to the Leverkusen presence in the back line.
Comfortable at right or centre-back, former Schalke skipper Höwedes will hope his injury troubles clear up and he can impress in Serie A with Juventus this term if he is to reprise his role in the World Cup-winning side.

Given that he’s only just returned to action with Dortmund, Julian Weigl will no doubt be pushing the midfield in options 1 and 2 once he is back at full fitness. The same goes for the goalscorer in the final against Argentina in Rio in July 2014, Mario Götze, who has shone in the BVB midfield of late following his return from metabolic disturbances.
Löw is also a fan of Amin Younes’ trickery: the former Borussia Mönchengladbach man offers the option of playing with a genuine winger. Julian Brandt adds to the Leverkusen connection, and could well push for more regular international recognition if he continues to impress at club level.
Up top, Lars Stindl has impressed since being included earlier this year: although no spring chicken at 29, the Gladbach skipper boasts plenty of Champions League experience and underlined his big-game mentality by scoring the winner in the Confederations Cup final this summer.
There was no real need to scrape the barrel for the fourth variation – wait until you see the list of absentees! Matthias Ginter stands as the sole survivor from 2014, but every single one of these players has represented their country at either senior or U-21 level.
Germany’s defensive strength in depth is underlined in the final line-up: two of the Bundesliga’s most reliable centre-backs, Willi Orban and Ginter, only appear on the periphery of Löw’s thinking, although both will no doubt fancy their chances of a spot on the plane to Russia if they continue their barnstorming form.
Ginter, in particular, looks to have benefited from his summer move to Gladbach and is back to his best thanks to playing more regular football.
A youthful, well-balanced midfield comprises Kerem Demirbay and Mahmoud Dahoud, whose fine start to life at Dortmund means he will surely be pushing for a first cap sooner, rather than later.
Another youngster to have had a fine start to life in Dortmund is Maximilian Philipp: if he continues his rich goalscoring form, he’ll be pushing for Reus’ place in Löw’s first-choice XI. Although the Germany coach is not a natural risk-taker, he has always been willing to reward players impressing domestically, and the 23-year-old is doing just that this season, having scored four goals already.
Up top, Wagner's wonderful goal against Northern Ireland pointed to his qualities: the Hoffenheim striker, who won the European Under-21 Championship back in 2009, has experienced a renaissance in the Bundesliga, giving him a new lease on life on the international circuit. Although 29, four goals in as many international games is an outstanding record.
There’s still a year to go until Joachim Löw has to consider making a final cut for his 23-man World Cup squad, but the array of talent he has at his disposal is enviable to say the very least.
