Xabi Alonso's treble-chasing team also stretched its European record unbeaten run across all competitions this season to 51 matches.

Victor Boniface intercepted a ball from Augsburg keeper Tomas Koubek to tap in for the lead in the 12th minute before Robert Andrich, part of Germany's UEFA Euro 2024 preliminary squad, doubled the advantage from close range.

Augsburg cut the deficit when Mert Komur scored a brilliant goal just after the hour, but nothing was going to spoil Leverkusen's title-winning party.

Leverkusen captain Lukas Hradecky made a smart stop to maintain Leverkusen's clean sheet, as the Bundesliga champion held on to make history.

Alonso's team, which faces Atalanta in the UEFA Europa League final on Thursday (AEST) and also takes on Kaiserslautern in the DFB-Pokal final on 26 May (AEST), finished on 90 points, 17 ahead of second-placed Stuttgart and 18 ahead of Bayern Munich, which lost 4-2 at Hoffenheim in its final game.

Alonso's men are now just two wins away from unprecedented success.

Leverkusen has become only the second team in Bundesliga history to not lose a single point from winning positions in a season, matching a feat Bayern managed in 2011-2012. 

It has won 45 points in 17 home games in the Bundesliga this season and remained unbeaten at home for only the second time, after 1999-2000. 

Leverkusen is the second club in league history to reach the 90-point mark, after Bayern (90 points in 2013-2014 and 91 points in 2012-2013).
