League One strugglers Crewe Alexandra are running the rule in training over Federico Bessone, having offered the Argentine full-back a week's trial.
Bessone, 30, first came to the United Kingdom in 2008 when he joined Swansea City from Espanyol on a free transfer.
He has since also turned out for Leeds United, Charlton Athletic, Swindon Town and Millwall, as well as spending time on the books at Oldham Athletic.
"We're having a look for a few days," boss Steve Davis told BBC Radio Stoke.
"He's a free agent, although he's been back training with Swansea."
Alex already have Bessone's former Swansea City team-mate Alan Tate with them on a three-month loan.

"He was put to us before Alan came," added Davis. "But he knows him from having played with him and we said we'd take a look, with him being a free agent."
Meanwhile, loan striker Danny Haynes and defender Harry Davis are being considered to start in Saturday's trip to Crawley, both having featured in Monday's Under-21 game at Nottingham Forest.
Davis, son of Alex boss Steve, is fit again after a seven-month absence through injury and would be an obvious straight replacement for youngster George Ray, who is now suspended for three matches after being sent off for dissent in Saturday's 1-0 home defeat by Sheffield United.
Crewe are also waiting to check on midfielder Brad Inman, who was discharged from hospital on Saturday evening after an X-ray on his neck following a clash of heads with Blades defender Chris Basham which left him with suspected concussion.
But they will also go to Crawley without fellow midfielder Anthony Grant, who ran up his fifth booking of the season last Saturday to earn a one-game ban.
