Armand Traore has joined Queen's Park Rangers on a three-year deal for an undisclosed fee.
Traore, 21, made 32 appearances for Arsenal, after joining from Monaco as a youth player in 2006.
His competitive debut came at just 17, against West Bromwich Albion in the Carling Cup. And he went on to feature in all major competitions for the Gunners.
The French left-back had season-long loan spells with Portsmouth in 2008/09 and, last term, with Juventus. He has represented France at Under-17, Under-18 and Under-19 level.
Everyone at Arsenal Football Club would like to wish Armand well for his career at Loftus Road.
