Champions Bayer Leverkusen battled past hosts Borussia Dortmund 3-2 with two goals from Patrik Schick on Friday to move within a point of leaders Bayern Munich with a sixth straight league win.

In a frenetic opening the visitors struck three times in the first 19 minutes as they enjoyed a perfect start to the year with the league resuming following a three-week winter break.

Dortmund, who twice cut the deficit, had fielded a largely makeshift team due to flu and injuries in what was their first home loss of the season.

A last-minute backline had to be cobbled together after defenders Waldemar Anton, Emre Can, Ramy Bensebaini and Nico Schlotterbeck were all ruled out along with long-time injured Niklas Süle.

It showed instantly with Leverkusen winning possession after some high pressing and Nathan Tella completing the move to give the visitors the lead after 25 seconds.

Dortmund had no time to regroup with Leverkusen scoring again in the eighth minute and striker Schick sliding in to complete a textbook counter-attack.

The hosts briefly recovered and pulled a goal back through Jamie Gittens four minutes later but Schick restored Leverkusen's two-goal cushion in the 19th minute with a fine finish at the far post after yet another quick break.

The Czech international, who had also scored four times in the last game of the year against Freiburg on Dec. 21, has now bagged 11 league goals this season.

The hosts hardly had any chances in the second half but were thrown a lifeline when Serhou Guirassy converted a 79th minute penalty.

Leverkusen survived late Dortmund pressure thanks mainly to some superb defending by Edmond Tapsoba and Piero Hincapié, to hold on and move up to 35 points, one behind leaders Bayern, who travel to Borussia Monchengladbach on Saturday.

Dortmund's first home loss of the campaign kept them anchored in sixth on 25 points.
