Barcelona forward Raphinha will miss Sunday's Clásico against Real Madrid after suffering a setback in his return from a hamstring injury, a source told ESPN.

Robert Lewandowski and Raphinha stand as critical components in head coach Hansi Flick's strategy, yet they will be unavailable as their team squares off against Real Madrid in El Clasico.
