Rayane Belaid Khelil was born on 11 February 2005 in Orihuela, Alicante, Spain. He came through Atlético Madrid's youth ranks and currently plays for the B team, Atlético Madrileño, with intermittent senior matchday inclusion under Diego Simeone — 134 La Liga minutes across two senior appearances during 2025–26.
Belaid has won the División de Honor Juvenil with Atlético's U19 in 2023–24 and the UEFA European Under-19 Championship in summer 2024 in Northern Ireland with Spain's U19 squad. He has dual-capped at youth level for both Spain and Algeria.
His listing at Atlético is as forward in some sources and midfielder in others — reflecting a versatile profile that operates across the front line and as an attacking midfielder. He combines pace, dribbling sharpness, and direct attacking intent — qualities that suit the modern wide-forward archetype Atlético have steadily added to their pipeline. His next development stage will likely involve expanding senior minutes or a developmental loan to a competitive league.
