William Saliba is a French centre-back who became a key player for Arsenal after breaking into the first team, and supporters turned his surname into a short, repeatable terrace chant. The chant spread through matchday videos, fan compilations and social media edits, where the crowd cheering and rhythmic repetition made it easy to reuse. It remains popular because it works as shorthand for a strong defensive performance, giving Arsenal fans a simple way to celebrate clean sheets, tackles and blocks in short clips.
