Alex Song has completed his £15million move to Barcelona from Arsenal.
The Cameroon international successfully passed his medical at Barca on Monday and put pen to paper on a five-year contract with the Primera Division giants.
Song, whose contract has a buy-out clause of 80million euros (£63million), will now join his new team-mates for the official team presentation at the Joan Gamper Trophy at the Nou Camp, where the Catalan club face Sampdoria on Monday night.
