After Wolfsburg acquired fellow Bosnian international Zvjezdan Misimović in July 2008, Džeko's performances improved significantly in the 2008–09 season. During the first half of this season Edin scored five goals and added seven assists, but after the winter break entire team improved significantly, with Džeko scoring 21 goals and adding three more assists. This was especially visible during the 10 games winning streak from 7 February to 26 April 2009, in which he scored 11 goals and added 1 assist. In May 2009 Džeko scored hat-trick against 1899 Hoffenheim, and again, just two weeks later, against Hannover 96, contributing overall 26 goals and 10 assists in 32 league matches to the team title winning 2008–09 campaign. His goal tally was second only to teammate Grafite, with whom he formed the most successful strike duo in Bundesliga history, and with the team's main assists and key pass provider, Zvjezdan Misimović, who himself broke longstanding Bundesliga record in assists by providing 20, they formed "the magic triangle". Wolfsburg ended the season as Bundesliga champions for the first time in the club's history. They finished two points clear of their title rivals for that season, Bayern Munich, whom they defeated 5–1 a month earlier, in memorable game with Džeko and Grafite scoring two goals each with later scoring his second and team's fifth with memorable backheel, and in which Wolfsburg, in third place at that point, exceeded Bavarians in second to take decisive lead for the first time and went through to keep the league top spot for the rest of the season eventually winning it.
