Modeste M'bami has been given the opportunity to try and earn a contract with Wigan.
The Cameroon midfielder has been looking for a new club since the expiry of his Marseille deal earlier in the summer.
He has been linked with a possible switch to Turkey, while there have also been reports of interest from England and Spain.
Latics manager Roberto Martinez now looks set to sign the 26-year-old after inviting him to the DW Stadium for a trial.
Martinez is fully aware of M'bami's qualities but insists he will still have to prove he is worthy of a deal.
"Modeste has a great pedigree and a great curriculum with top teams around the continent," said Martinez.
"He can control the tempo of the game with his ability and experience.
"He has a sharp brain, can see a pass quickly and can operate in a few positions around the midfield area.
"We'll be assessing him over the next week and see what happens."
