Japan midfielder Shinji Kagawa set up three goals as Borussia Dortmund demolished Augsburg 5-1 in the Bundesliga on Sunday.

Kagawa provided two for Marco Reus in the first half before assisting with another right before the end of the game for Pierre-Emerick Aubameyang, who scored a hat-trick as Dortmund remained second and seven points behind leaders Bayern Munich.

"We're having great combinations. But we could have suffered if we were playing stronger sides," said Kagawa, who was involved in four of five goals.
