The Bundesliga champions, Bayer Leverkusen, battled past their hosts Borussia Dortmund with two goals from Patrik Schick on Friday to move to within a point of the 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.
