The club has already captured the signature of Iranian striker Redha Enayati, who has now joined up with Iran as part of their World Cup qualifying campaign.
Enayati, who played for Emirates club for the last two seasons, will join Al Nasr in July to start preparing for the new season.
The signing of Enayati and Maadanchi came after a request from team coach Luka Bonacic, who worked in Iran for four years and knows the Iranian players well.
The club's last Iranians, Farhad Majidi and Arash Borhani, were not successful and the club terminated their contracts before the end of the season 2006-2007.
Bonacic is now looking for a third Iranian with his sights set on a defender, following Al Nasr's poor form at the back last season. The club conceded 39 goals in 22 league matches during the campaign.
Defender needed
The Croatian coach has asked the club's board to sign a strong Emirati defender, otherwise he will be looking for an experienced defender from Iran, who can lead the backline as the club gears up for the challenges of the professional league next season.
"Redha Enayati is a good striker and he did well last season. "He is a leader on the field and that is what Al Nasr needs," said the Croatian.
Al Nasr have terminated the contracts of Nigerian players Edahor and Goodwin, who showed poor form during last season's league campaign.
Meanwhile, goalkeeper Salim Abdullah has returned to Al Shabab. Salim performed poorly during the two seasons he turned out for Al Nasr as senior goalkeeper.
