The 28-year-old Egyptian has spent the majority of his playing career in Germany, joining Dortmund from Hamburg in 2008 following spells with fellow Bundesliga outfits Mainz and Werder Bremen.
Zidan, who has netted seven goals in 33 appearances for his country, has recently returned from Angola having helped the Pharaohs win a third successive Africa Cup of Nations crown, scoring in the semi-final before setting up the winner against Ghana in the final.
And, according to the player's father Abdullah, Zidan's consistently solid performances have caught the eye of Premier League heavyweights Arsenal and Manchester United and European champions Barcelona.
"Arsenal, Manchester United and Barcelona have talked to Mohamed's agent," he told Dream TV.
