Celtic have invited FK Pribram duo Jakub Stochl and Antonin Fantis to the club for a trial period. The Bhoys signed Milan Misun from the Czech outfit earlier this year and are considering handing deals to two more youngsters.
22-year-old defender Stochl and versatile forward Fantis, 17, have also attracted interest from Italy.
"Such an interest, not only of Celtic of course, is a big evaluation of the work in our club," Pribram chairman Jaroslav Starka told iDnes.cz.
"For instance, Fantis was trialled by Celtic a year ago. They were speaking of him highly but he was only 16 back then so it was better for him to go back to the Czech Republic and continue his career there.
"That is why we set up another trial for him. Moreover, they want to have a look at one of the most talented Czech stoppers, Jakub Stochl."
Ondrej Chovanec, the agent for both players, has warned Celtic to expect competition from elsewhere for their signatures.
"Pribram are developing some very talented footballers," said Chovanec.
"For instance, Stochl is being tracked also by Catania while Fantis was tested by Juventus at the start of November."
