Bayer Leverkusen are beating Borussia Dortmund at half time in their Bundesliga match this evening.
Dortmund threatened first when Pierre-Emerick Aubameyang raced to the byline before crossing the ball to Robert Lewandowski, who saw his shot blocked by Bernd Leno.
Emre Can cut in from the left for the away side, but his effort was saved.
However, Sami Hyypia's team were soon in front. Gonzalo Castro pounced on a loose ball and released Son Heung-Min, who rounded Roman Weidenfeller and tapped in.
Chances were at a premium after that, although Leno saved from Lewandowski and Jens Hegeler fired over the bar from the edge of the box.
