Satka was the surprise name among the 23 Newcastle players who left for a tournament in New Zealand yesterday.
The 18-year-old Slovakian has been likened to United captain Fabricio Colccini by manager Alan Pardew, who gave Satka a long-term contract earlier this year.
Satka, signed from Dubnica two years ago, was also among the substitutes for their final game of the season at Liverpool.
"Lubo is, for me, a player beyond his years - he's very calm," says Pardew.
"He's so level-headed and technically good. He's got a great chance for us. We've really got our fingers crossed for him."
