Arsenal have secured Borussia Dortmund's Sven Mislintat as their new head of recruitment.
Chief scout Steve Rowley has stood down from his post after 25 years with the north London club.
Mislintat had been at Dortmund for almost a decade, during which time the Bundesliga club recruited star names such as Robert Lewandowski, Pierre-Emerick Aubameyang, Shinji Kagawa and Ousmane Dembele.
"We are delighted that Sven is joining us," said Arsenal manager Arsene Wenger.
"Identifying and developing talent is a core part of our philosophy and Sven has an outstanding track record over many years.
Mislintat will work alongside Wenger and chief executive Ivan Gazidis to unearth new talent for the Gunners.
Long-serving scout Rowley will continue to work with Arsenal in a consultancy role despite stepping down from his permanent position.
"We would like to thank Steve Rowley for all his hard work over many years for the club," Wenger told Arsenal's official club website.
"He has been a key figure in our recruitment of so many top players and has travelled thousands and thousands of miles, watching hundreds of games for us during his time at the club. We wish him well for the future."

Mark Noble has urged West Ham's unhappy supporters to get behind their struggling team.
The away fans vented their anger towards the club's board and certain players during Sunday's 2-0 defeat at Watford.
It was a nightmare first game in charge for new manager David Moyes and left the Hammers marooned in the drop zone.
Skipper Noble told West Ham TV: "It's a very difficult situation for us.
"The fans show their emotions, and rightly so because they're not happy and they pay a lot of money to come and watch us.
"I know it's hard, I know they're frustrated, and we are too because we know we're better than what we're showing, but I urge them to stick by us and hopefully the good times will come back.
"As much as we're not performing on the pitch at the minute, we need them to stick by us."

The Hammers suffered a 2-0 defeat at Watford on Sunday in David Moyes' first match in charge, with goals from Will Hughes and Richarlison settling the match at Vicarage Road.
It seems some supporters have been taking their grievances too far though, with the Essex Police Force Control Room urging them to stop using the emergency number.
A tweet from the @EPControlRoom account read: "Ringing 999 because @WestHamUtd have lost again and you aren't sure what to do is not acceptable! It is a complete waste of our time. #999foremergencies only."
Sections of the visiting support chanted "sack the board" during the match as the team remained 18th in the Premier League table.
