Arsenal captain Thomas Vermaelen has joined Barcelona after an agreement was reached between the Catalan side and Arsenal for up to £15million and on a 5 year deal with the defender. The Belgian international has found first team opportunity hard to come by recently most especially last season when he lost his place to Per Mertesacker and Laurent Koscielny. He has also struggled with injury in recent times and has now decided to start afresh in La liga. Manchester United was revealed as part of group of bidders for the defender but Arsene Wenger revealed earlier he would prefer to sell abroad than allow the player remain in England. Other defenders are being lined up as replacement and they include Manchester City's Natastic, Real Madrid's Alvaro Arbeloa among others. As the transfer window still remains open till first of september, there is still room for additions to the team.
