Originally scheduled to leave at the end of the season, the Spaniard’s contract is now anticipated to last until 2027.
In December 2019, the Gunners named Arteta, a fellow countryman Unai Emery’s coach at Manchester City under Pep Guardiola, their new manager.
At the end of the 2019–2020 season, he managed Arsenal to victory in the FA Cup final, earning his first major title.
It’s anticipated that Arteta’s new contract will be official before Sunday’s north London derby against Tottenham.
In the last two seasons, Arsenal has trailed Manchester City in the Premier League.
Arsenal is now in fourth place after three games this season. They won their opening two games against Wolves and Aston Villa before Brighton held them to a tie.
During his playing career, Arteta, a former midfielder, made 150 games with the Gunners and captained the team.
