Tasnim - Grasshopper goalkeeper Daniel Davari completed a move to Arminia Bielefeld on Wednesday.
No financial details of the deal have been revealed.
Davari started his career with FSV Mainz 05 II and then joined Eintracht Braunschweig.
The 27-year-old Iranian-Polish goalie was invited to Team Melli after pretty good performance in Bundesliga.
Davari was a member of Iran football team in the 2014 FIFA World Cup but was an unused substitute with Alireza Haghighi starting all of the three matches for Iran.
