Former Sevilla midfielder Isco's move to Union Berlin has stalled.
The free agent has been in talks with the Germans about a move to the Bundesliga.
Mundo Deportivo says Isco was undergoing a medical when the negotiations suddenly broke off.
The former Real Madrid star remains in contact with Union Berlin, but is now expected to look elsewhere for his next club.
Being a free agent, Isco is under no pressure to find a new team before tonight's transfer deadline.
