Arsenal has completed a deal to sign Borussia Dortmund chief scout Sven Mislintat, the club announced, with a fee of almost €2m reportedly agreed upon between the clubs.
Mislintat was under contract at Dortmund until 2021, but now makes the switch to North London.
The 45-year-old has been credited with unearthing several of the Bundesliga club's most successful players in recent years, including the likes of Robert Lewandowski, Pierre-Emerick Aubameyang, Shinji Kagawa and Ousmane Dembele.
Arsenal approached Mislintat last week with a view to appointing him as a potential replacement for Steve Rowley, who exits his role but will remain with the club in a consultancy basis.
The Gunners are said to be looking to modernize their approach to transfers, and Mislintat has been identified as the ideal man to begin the process.
“We are delighted that Sven is joining us," Wenger said in a club statement. "Identifying and developing talent is a core part of our philosophy and Sven has an outstanding track record over many years. We look forward to him taking our existing recruitment approach forwards.”

Bayern Munich attempted to appoint the German scout as its new technical director in August, but was unsuccessful.
Dortmund's scout has emerged as one of the most sought-after talent spotters in Europe having achieved a remarkable success rate in Germany.
He has a close relationship with sporting director Michael Zorc, but fell out with former coach Thomas Tuchel in January 2016 when a move for Atletico Madrid midfielder Oliver Torres collapsed.
