Alexander Hleb has completed his move from Arsenal to Barcelona after signing a four-year contract with the Catalan giants.
The Belarus international landed in Barcelona on Wednesday morning and after spending the day undertaking various medical tests sealed his switch this evening.
The 27-year-old midfielder will cost Barca an initial €15 million, rising to €17 million depending on the club's success during Hleb's spell.
The buy-out clause in Hleb's contract with Barca has been set at €90 million.
Hleb, who has been linked with a move to Barca all summer, becomes the fifth signing of the close season for the Nou Camp club, who will be under the guidance of Pep Guardiola next term after he replaced Frank Rijkaard as coach at the end of 2007-08.
Already brought in by Barca are Sevilla duo Seydou Keita and Dani Alves, as well as Manchester United defender Gerard Pique and Martin Caceres fromVillarreal.
Hleb spent the last three seasons at Arsenal after joining the Barclays Premier League side from German club Stuttgart. Prior to that he played for BATE Borisov in Belarus.
