VIDEO: Lewandowski scores 90th-minute winner, 10-man Bayern sneaks past Hoffenheim

Berlin - A 90th-minute Robert Lewandowski goal saw 10-man Bayern Munich earn a dramatic 2-1 win at Hoffenheim on Saturday after conceding the joint fastest goal in Bundesliga history.

The Polish striker sealed the champions' comeback after Germany Under-21 striker Kevin Volland had opened the scoring with just nice seconds gone, darting onto David Alaba's loose pass and drilling his shot home at the Rhein-Neckar-Arena.

Volland's goal equalled the previous record set by Bayer Leverkusen's Karim Bellarabi on the opening day of last season at Borussia Dortmund.

Bayern equalised when a Douglas Costa shot rocketed off the hands of Hoffenheim goalkeeper Oliver Baumann and Thomas Muller jabbed home the rebound with his knee on 40 minutes.

Hoffenheim wasted the chance to claim a historic first win over Bayern at the 15th attempt when Eugen Polanski blasted his penalty attempt off the post after Jerome Boateng's handball saw the German international sent off for a second yellow card on 72 minutes.

Bayern claimed the dramatic winner when Costa fired in a superb cross, Mario Gotze let the ball roll and Lewandowski drilled home his shot to keep Bayern top of the table, having routed Hamburg 5-0 on the opening weekend.
