The phrase "Arsenal DNA" refers to a set of values, playing styles, and cultural traits that are deeply embedded in the identity of Arsenal Football Club. It symbolizes the club's traditional approach to football, characterized by attacking play, technical skill, and a commitment to youth development.

The origins of this term can be traced back to the legacy of Arsène Wenger, the club's long-serving manager from 1996 to 2018. Wenger
revolutionised English football with his emphasis on attractive, possession-based football, meticulous attention to player development, and an emphasis on nutrition and fitness. Under his guidance, Arsenal became known for
their fluid, attacking style, often referred to as "Wengerball." This style was seen as part of the club's DNA, something that should be maintained regardless of changes in management or players.

"Arsenal DNA" also encompasses the club's focus on promoting young talent from their academy, with an emphasis on integrating these players into the first team. This approach has been a hallmark of the
club's philosophy, contributing to its reputation for nurturing homegrown talent.

In a broader sense, "Arsenal DNA" is invoked by fans, players, and pundits to describe a way of doing things that is distinctively Arsenal—whether it's playing attractive football, showing
resilience, or adhering to the club's values of integrity and respect​.
