Edu, 46, resigned in November after five years with the Gunners who appointed their former player as the club's first ever technical director in 2019 before his promotion as sporting director in 2022.
The Spaniard signed the likes of Merino, Isak, Martin Odegaard and David Silva during his seven-year spell at Sociedad - he also worked out deals with Arsenal involving Kieran Tierney and Nacho Monreal.
ARSENAL are planning to hire a new sporting director to replace Edu Gaspar next month.
The same goes for Arsenal interim sporting director Jason Ayto, who was promoted after Edu's departure.
Berta is one of the main figures that turned Atletico Madrid into LaLiga and Champions League challengers thanks to his stunning 12-year stint working with manager Diego Simeone until his exit last month.
