Jan Dvořáček — centro papiro — was one of the best forwards that Czechoslovakia produced during this 20s. At his peak of performances, Dvořáček could also be mentioned as one of the best insiders in Europe. He was the best name in AFK Union Žižkov and one of the most important players of the, yet in transition, A.C Sparta. For the Czechoslovakia National Team, Jan Dvořáček scored a total amount of 10 goals in only 12 matches.

Dvořáček was physically a weak player but a very determined & energetic one. After the thrashing of Barcelona-Sparta, 06/01/1926, he received the name of centro papiro from the Spanish press, due to his extremely low weight and thinness.

Fast, with great technique and extraklassisz tactical knowledge made Jan Dvořáček a dangerous forward to deal with. He knew when to infiltrate or to think on the next play. Dvořáček — like Alfréd Schaffer — while playing as centre-forward, used to play more with the insiders, but also used to connect with both wingers. His fast combinations with the inside trio would give some trouble to the opposition's defense. 

Tatically speaking, yes; he was an smart and opportunist player who timed his infiltrations inside the defensive system. Dvořáček achieved some great performances as centre-forward, but, back in the day, due to Sparta's play style, some thought that his individualist play did not match Sparta's old style - the style which had Pilát as the suprassumo. Dvořáček used to put little emphasis on fellow players, trying to achieve everything himself, which sometimes worked for him. He was also very moody and used to destroy some actions. Dvořáček was, indeed, a play executor, and not a chance creator. He was much more appreciated as an insider.
