Derby County have handed trials to ZTS Dubnica defender Martin Klabnik.
Klabnik is trialling with Derby's U19 team and his agent, Emil Kovarovic, told SITA: "The first-team manager (Billy Davies) is expected to see him in training.
"I recommended Martin to Derby after the summer's Under 17s tournament in Hungary.
"The English team were watching him during the Under 17s' qualifier in Scotland and two weeks ago they arrived to see him in a domestic league game."
