Ander Herrera (Manchester United and Spain)
Such is the depth of quality in the Spain midfielder, Ander Herrera is yet to get a full cap for La Roja, despite Manchester United having shelled out more than £30 million to sign him from Athletic Bilbao this summer. A reasonable start to life at Old Trafford may have caught the attention of manager Vicente del Bosque, however, and he may well see Herrera as worth introducing to the squad as Spain look to plan for life after Xavi and Xabi Alonso.
