Aberdeen have handed a trial to former Bayern Munich youth keeper Dan Twardzik. Also on trial at Pittodrie is New Zealander Te Atawhai Maurice Hudson Wihongi - a friend of Dons striker Rory Fallon.
A statement on the club's website read: "With the January transfer window just around the corner, the manager is constantly reviewing ways in which to develop the current squad and will open the door to a number of trialists over the course of the next few months."
