Joachim Low is confident there is more to come from his Germany team after seeing them march into the World Cup finals in Brazil.
A 3-0 victory over the Republic of Ireland in Cologne ensured that the Germans will finish top of Group C with a game to spare, and they head for Sweden on Tuesday already looking ahead to their adventure next summer.
Asked if his squad has the potential to be the best German side ever, Low said: "I look at previous campaigns, especially during Euro 2012. The team is more solid, more stable and more compact in defence.
"I used this campaign to make my team more stable. It hinges around the opponent you play, they will have a major role in making games attractive or nice to watch for the spectators.
"Of course we do have some things to tackle. Defensively, there is room for improvement. But the matches against Austria and today really came close to perfection."
For all the home side dominated possession and were repeatedly thwarted by a stubborn display by Ireland keeper David Forde, they did not kill the game off until injury time.
Sami Khedira had given them a 12th-minute lead with a deflected shot and Andre Schurrle doubled the advantage 13 minutes after the restart, but not before Ciaran Clark had hit the bar at the other end and Anthony Stokes gone perilously close to an equaliser.
Mesut Ozil eventually wrapped things up in the 92nd minute to send his side to Sweden with a score to settle.
Germany led the Swedes 4-0 at home in October last year, but only ended up with a point after Zlatan Ibrahimovic inspired a remarkable fightback.
Low said: "Four-four after being 4-0 up, you will not be the media darling for that weekend.
