Crewe have handed a trial to striker Pavol Suhaj, who plays for Slovakian side AS Trencin.
The 24-year-old, who has enjoyed a previous spell with Patraikos Patras in Greece, will spend four days with Dario Gradi's side this week in the hope of securing a contract.
Trencin manager Robert Rybnicek said: "Pavol Suhaj has a contract with our team for one more year, so representatives of the English club have to come to agreement with us as well.
"He will come back to Slovakia after the tests sure so he can play in a game of the first round of Corgon Liga vs Banska Bystrica on Saturday."
