The highly-rated 15-year-old full-back will head to north London after rejecting a contract offer from the Camp Nou outfit
Arsenal are close to completing a move for Barcelona youngster Joel Lopez after fighting off interest from Premier League rivals Liverpool.
The 15-year-old Cadete A left-back has been at the Catalan giants since the age of seven and is described by reports in Spain as a 'mature, attacking full-back who can be used as an offensive weapon'.
Raul Sanllehi, Arsenal's head of football relations who left Barcelona to join the Gunners at the start of the year, is likely to have played a part in persuading Lopez to sign for Arsenal over Liverpool, who have also showed a keen interest.
