Joachim Low's side has been in imperious form in Group C, scoring 43 goals and conceding just four. 

Leon Goretzka opened the scoring early on with an impudent backheel before Azerbaijan scored an unlikely equaliser through Ramil Seydaev to go into the break level.  

Die Mannschaft turned on the style in the second half, though, as goals from Sandro Wagner, Goretzka, Emre Can, and an own goal from Badavi Huseynov ensured it ended its qualifying campaign with a flourish.  

The only negative for the host was the first-half withdrawals of Niklas Sule and Shkodran Mustafi through injury.

Low made seven changes from the side that beat Northern Ireland 3-1 on Friday (AEDT), but his new-look team gelled immediately and was ahead inside eight minutes.

Joshua Kimmich's deep corner fell at the feet of Goretzka, who - despite having his back to goal - executed an audacious backheel into the top corner of Kamran Aghayev's net.

The visitor responded well to the early setback, though, and should have been level shortly after. Seydaev played in Richard Almedia, but the Qarabag forward took too long on the ball and was muscled out before he could get a shot away.

Wagner then somehow contrived not to score just after the half-hour mark. Thomas Muller's low cross was met by the unmarked Hoffenheim striker six yards out, but his effort was deflected onto the post by Aghayev. The rebound then crashed against the hapless Wagner's knee and screwed agonisingly wide from point-blank range.

Wagner's misfortune was Azerbaijan's gain, however, as the visitors pulled level in the 34th minute.

Mustafi pulled up injured going for the ball, allowing Seydaev a free run into the area, where he duly turned substitute Antonio Rudiger before drilling a low shot past Bernd Leno from a tight angle.

Germany looked to bounce back immediately and Wagner was again denied by Aghayev, this time from a powerful header at the back post, while Leroy Sane inexplicably drilled wide from close range on the stroke of half-time. 

Germany's fluid attacking play was on show again immediately after the restart as some clever exchanges on the edge of the area played in Julian Brandt. The Bayer Leverkusen winger's initial effort was blocked by Aghayev and his follow-up dribbled just past the upright with the Azerbaijan goalkeeper stranded.

The host's bright start to the second period was rewarded nine minutes in as Wagner netted his fifth goal in as many appearances for his country.

The 29-year-old met Brandt's deep cross with a thumping header, which crept over the line despite the best efforts of Ruslan Abisov to clear.

Lars Stindl then hit the post with a dipping half-volley before two goals in three minutes killed any faint hopes Azerbaijan might have had of a comeback.

First, Rudiger's header from Kimmich's corner was put into his own net by the unfortunate Huseynov and then Goretzka scored his second, turning in Leroy Sane's low cross from close range.  

Germany then hit a fifth as Liverpool midfielder Can scored his first international goal with a thumping long-range drive.

There was still time for Azerbaijan's Magomed Mirzabekov to crash a shot against the post in the closing stages, but it was fitting that the final goal of the game was Can's memorable strike.
