Arsenal's midfielder Alexander Hleb is in Spain to undergo the medical tests in order to complete his move to Barcelona. Skysports.com claimed that the Catalan giants are set to announce the signing in the next couple of days after reaching an agreement with the Gunners. The 27-year old player has been linked with a move away from Emirates Stadium and clubs like Real Madrid, Barcelona and Inter Milan have revealed their interest. “In life, everything changes. I believe that there are 10 top clubs in world football, and when a couple of clubs are interested in you and offer better terms, I believe that others would have done exactly the same," the Belarus midfielder said. “But Arsenal is dear to me, I am grateful to Wenger for everything he has done for me." Barca are willing to strengthen their midfield after Deco's departure while Ronaldinho's future is uncertain at the Nou Camp. Hleb is set to become Josep Guardiola's fifth signing after Seydou Keita, Daniel Alves, Gerard Pique and Martin Caceres.
