Four Slovakia stars have been punished for partying before their nation's World Cup qualifier against Liechtenstein, local media reported on Friday.

Midfielders Marek Hamsik and Karim Guede, plus wingers Vladimir Weiss and Miroslav Stoch breached their squad's strict rules and went to a Bratislava disco last Saturday when they should have been resting a day after Slovakia's 1-1 away draw with Lithuania.

Joint coaches Stanislav Griga and Michal Hipp punished them with a salary cut and the four will also have to play for free in the eight remaining qualifiers, the Slovak tabloid Novy Cas said.

The stalwart players' night out did not leave Slovakia with red faces, however, as they beat minnows Liechtenstein 2-0.

The quartet are among the biggest names in Slovakia's squad, and all ply their trade in the foreign top flight.

Hamsik and Weiss play for Italian clubs Napoli and Pescara, while Guede is at Germany's Freiburg and Stoch with Fenerbahce in Turkey.
