Early this month, Zidan said – shortly after becoming a German citizen by naturalization – that he might not carry on his career with the Bundesliga side.

The 29-year-old, who's targeted by Cairo giants Ahli, cited lack of first-team football as a reason to consider a new move.

Twenty-two-year-old Perisic, who was named the best Belgian Jupiler League player in the 2010-2011 season, joined Dortmund on a five-year deal.

He fills the same position of Zidan, which further cast doubt over the latter player's future with Dortmund.

Zidan's campaign this term was largely affected by a long-standing knee injury sustained last year.
