France international Samir Nasri claims he has completed his transfer from Marseille to Arsenal.
Gunners boss Arsene Wenger is reported to have paid £15.8million to secure the 21-year-old's services on a four-year deal.
Nasri underwent a medical in London last week, following France's elimination from Euro 2008.
"We inform you that Samir won't be an Olympique de Marseille player next season and that he has signed a four-year contract with London club Arsenal," read a statement on Nasri's personal website.
Nasri made two substitute appearances for France, against Italy and Romania, at Euro 2008 as Les Blues failed to progress from the group stage.
The attacking midfielder has also represented France at under-16, 17, 18, 19 and 21 level. He won the 2004 Under-17 European Championship with Les Bleus, scoring the winning goal in the Final.
Nasri won his first cap for France's senior team in March 2007 in a friendly against Austria and scored his first international goal in his third appearance for the senior team in a Euro 2008 qualifier against Georgia three months later.
