Leverkusen's 3-1 victory over Freiburg on Sunday puts them two points ahead of Bayern Munich, which had gone top only the day before.

Stefan Kiessling's 36th minute goal was his 13th of the season and the first of three goals in an action-packed four minutes.

Eren Derdiyok came next to make it 2-0 just a minute later, followed by Sami Hyypia in the 40th minute.

A goal in the second half by Freiburg's Felix Bastians wasn't enough to counter the powerful Bayer Leverkusen, who are still undefeated for the season.

Bayern Munich, who won 3-0 over Mainz on Saturday, slipped into the second place in the Bundesliga table with 42 points, followed by Schalke, Dortmund and Hamburg.
