Llera's only appearance for Blackpool came at Sheffield Wednesday
Sheffield Wednesday have signed defender Miguel Llera on an 18-month contract after he and Bojan Djordjic were released by Blackpool.
The pair joined the Seasiders on free transfers last summer but failed to hold down first-team places.
Llera, 32, had a successful loan spell with the Owls in November, winning all three of the games he started.
Former Manchester United and Plymouth midfielder Djordjic, 29, failed to make a senior appearance for Blackpool.
