Flick explored an alternative setup during training, shifting Jules Kounde into central defence, a role he has not regularly occupied in recent seasons, while deploying Ronald Araujo at right-back.
Nineteen-year-old Rayan left Vasco da Gama in Brazil's top flight, where he played just shy of 100 times scoring 25 goals, for the Vitality Stadium in an initial 25 million transfer. He's the son of former Vasco defender, Valkmar, who played for the club during their late-1990s peak.
