Swedish centre-back Sotiris Papagiannopoulos has joined Premier League side Swansea City on trial.
The 26-year-old is contracted to Swedish club Ostersunds FK so could only sign for the Swans when the transfer window reopens in January.
Swansea say Papagiannopoulos, who is of Greek extraction, will train with them for "a few days".
Ostersunds are currently sixth in Sweden's top flight, Allsvenskan, and play away against Kalmar on Saturday.
Swansea have a working relationship with Ostersunds, having signed forward Modou Barrow from them in 2014.
The Swans have already signed two central defenders this summer - Alfie Mawson from Barnsley and Mike van der Hoorn from Ajax - while former captain Ashley Williams has joined Everton.
