Zidan, who is trying to regain match fitness following knee surgery last year, started the game behind Robert Lewandowski and assisted the Polish forward with his first goal.

"I am satisfied with my performance. I made the first goal and was involved in the second," Zidan told Dortmund's website.

All goals were scored after the break by Lewandowski, Nuri Sahin, Antonio da Silva and Daniel Ginczek.
