ANDER HERRERA will buy himself out of his contract at Athletic Bilbao to force through a move to Manchester United. Bilbao have surprisingly rejected United’s £29m bid even though the offer meets the release clause in midfielder Herrera’s contract with the Basque club. Now, it is understood, Herrera will pay Bilbao the transfer fee with United re-imbursing him. A similar wrangle occurred when Javi Martinez left Bilbao for Bayern Munich two years ago.
