Borussia Dortmund striker Robert Lewandowski has hailed his side's spirit as they overcame Mainz 05 3-1 in the Bundesliga last weekend.

Dortmund were looking to bounce back following their home defeat to champions Bayern Munich and managed to do so through goals from Lewandowski and Pierre-Emerick Aubameyang.

"These three points are very important for us. We came through a difficult game and showed we're a good team who can also adapt and deal with injury problems," the Poland striker said after the game.

"We weren't at our best and we had a few problems. Mainz really got stuck in and made life difficult for us. After the break we changed things around a bit and it all improved."

Dortmund are third in the Bundesliga table having played 14 games so far this season.
