The Bohemka reference is a touch misleading in that Nitrianský signed for them in January and did not feature in any game for them for the second half of the season. This should perhaps raise some alarm bells as they avoided the drop from the Czech first league by a grand total of one point (you've got to feel for Hradec Králové, who went down on goal difference). Previous to that was a year and a bit with Slovan Liberec, who last season were a shadow of their former selves and finished mid-table, where they usually are in the top four or so.
Positives for this signing is the solid record that Nitrianský enjoyed in four years at Slavia Prague, however this was during some of the worst times in the club's history where they nearly got relegated. There are some pertinent similarities with the Scottish game in that he is a typical Czech RB in that he is a physical presence, and not (if I am led to believe) one of these guys whose going to bomb it upfield and try to grab goals. If you're looking at a player to try and sure things up at the back I can see this working out.
