An article from Czech newspaper Rude Pravo of 31-05-1950 about the match East-Germany 0-1 Prague XI
East-Germany: Birkner - Gödicke, Labant - Knefler, Straube, Breitenstein - Drognitz, Rappsilber, Franke, Schöne, Strapa.
Prague XI: Stojdl - Panec, Sirucek - Lexa, Zák, Kolský - Sirotek, Král, Hájek, Vokoun, Charvát.
I can make up this match must have been played on 29 May, as a part of a multi sports event, there were 70.000 spectators and the goal was scored in the 20th minute by Sirotek. Nevertheless, I don't see any name of Prague based players who played for Czechoslovakia the previous week against Romania as Menclík, Krásnohorský, Vlk, Kvapil, Zdárský and Preis.
