Mikel Arteta will now carry the title of Arsenal first-team manager instead of head coach as part of a restructuring that reflects his growing influence at the club.
Arteta, 38, was only appointed in December but an upturn in performances coupled with his leadership throughout the coronavirus pandemic has prompted Arsenal to effectively promote him.
As part of an overhaul which led to 55 non-playing staff redundancies, the exit of head of football Raul Sanllehi and a number of long-serving scouts, the club has also made Vinai Venkatesham chief executive.
Venkatesham, who was previously managing director, will oversee a three-man team responsible for all football affairs.
Arteta will work closely with technical director Edu and academy manager Per Mertesacker.
"He has walked into probably the toughest nine-month period this football club has had in its 134 year history," Venkatesham said of Arteta. "I say probably, but I checked with [life president] Mr. [Ken] Friar and he has been here for 70 of those years and he says it is the toughest period the club has ever had so, take it from him if you don't want to take it from me.
"During that period Mikel has lifted the spirits of fans, staff, players and driven this team to an FA Cup semifinal and an FA Cup final, winning that trophy and winning the Community Shield. That is no mean feat.
Arteta steered Arsenal to a 14th FA Cup success versus Chelsea last month and was pivotal in helping persuade Pierre-Emerick Aubameyang to agree a new three-year contract.
He was also a key figure in talks over a pay-cut which started soon after the United Kingdom went into lockdown.
Arteta is understood to have held talks with the first-team squad to convince them of the necessity to take a 12.5% pay cut for 12 months. The squad later received 5% back upon qualifying for the Europa League.
