Legia Warsaw fans were filmed arriving at the home stadium in the Polish capital to watch their team play against Slask Wroclaw on Sunday.
The game took place as the government allowed to restart Poland's top football league with supporters present at the match.
As a precaution, only a quarter of the seats were opened with no visiting fans allowed in the stadium.
Supporters were also required to wear masks and disinfect their hands.
Legia Warsaw won 2-0 with two goals from Valeriane Gvilia.
