Bayer Leverkusen's record-breaking run to their first Bundesliga title was no fluke, with a 16-month plan coming to fruition.

Austria's Christoph Baumgartner scored one of the fastest ever international goals inside seven seconds on Saturday and was then quickly followed by a similarly lightning strike by Germany's Florian Wirtz.

Florian Wirtz scored after 84 seconds as Bayer Leverkusen made it 38 games unbeaten in all competitions with a 3-2 victory in Freiburg on Sunday.

Nathan Tella and Florian Wirtz scored as Bayer Leverkusen beat 10-man Wolfsburg 2-0 on Sunday to edge their team closer to a maiden Bundesliga title.
