In November 2017, Arsenal appointed a new chief scout, with Sven Mislintat taking over at the club after 10 years with Borussia Dortmund.
The German sport scientist has already had an impact at the Emirates, bringing in new players during the January transfer window including names he had assessed and worked with during his time with the Bundesliga club.
Henrikh Mkhitaryan was brought to Dortmund from Shakhtar Donetsk in 2013 before moving to Manchester United three years later. The Armenia attacker was inconsistent at Old Trafford, but on Mislintat's advice has joined the Gunners where he can regain the form he showed with BVB.
