Swansea are eyeing a move for Napoli's Federico Fernandez according to the Daily Mirror.
The 25-year-old, who played for Argentina at the World Cup, is keen to move to the Premier League after becoming restless at Napoli.
He is expected to be the replacement for Chico Flores, who is on his way to Lekhwiya SC to join up with former boss Michael Laudrup.
Fernandez will cost the Swans around £8million if he is to become their seventh signing of the summer.
They are also interested in Celtic's Virgil Van Dijk, who is a backup should they fail to sign Fernandez.
