Egypt ace Zidan was granted German citizenship along with his Turkish teammate Nuri Sahin in the wake of Dortmund's league triumph.

"I applied for nationality as I live in Germany for years and I have past all tests and fulfilled all terms," he told Al-Hayat TV.

The 29-year-old cited lack of first-team football at Signal Iduna Park as a reason to consider moving away.

"I might not be with Dortmund next season; I don't want to waste another term on the bench," said Zidan, who was greatly hampered by a serious knee injury he had sustained last year.

"I was a regular before the injury but when I came back I turned into a third or fourth choice for the head coach (Jurgen Klopp)."
