Arsenal striker Folarin Balogun has completed his £38m move to Monaco.
Balogun underwent medical tests in Monaco on Tuesday and now returns to the league where he shone last year.
Balogun has not featured in any of Arsenal's Premier League squads so far this season.
Eddie Nketiah and Leandro Trossard have started ahead of USA international Balogun, despite first-choice striker Gabriel Jesus being out injured.
Balogun came through the Arsenal acadamy and was prolific at junior level for both club and country, before switching allegiance to play senior football for the USA.
