Arsenal technical director Edu has proven in recent transfer windows just how valuable he is to the club. The Gunners have endured their fair share of transfer mistakes with club-record signing Nicolas Pepe the obvious one, but under Mikel Arteta smart decisions have been made and the club are reaping those rewards this season.
The acquisitions of Ben White, Aaron Ramsdale and even Martin Odegaard, after his loan spell, were questioned but their recent summer business was arguably the biggest indication of Arteta's methods being implemented at Emirates Stadium.
Two players Arteta worked with closely at Manchester City were signed by Arsenal in Gabriel Jesus and Oleksandr Zinchenko for a combined total of £77million. Despite Jesus missing the last three months, both have proven to be superb acquisitions.
