8) Thomas Vermaelen (Arsenal to Manchester United)
Despite interest from Barcelona, it has been strongly suggested by Arsenal manager Arsene Wenger that there may be little he can do to prevent Thomas Vermaelen from leaving to join rivals Manchester United. The Red Devils are in need of new signings at the back, and the Belgian international is seemingly Louis van Gaal’s preferred option in that position, with his experience and proven quality at the top level, despite recently falling out of faovur at the Emirates Stadium.
