Serbian SuperLiga giants Red Star Belgrade have revealed that five players from the club have tested positive for coronavirus after playing numerous matches attended by thousands of individuals, the club said Monday.

FK Crvena zvezda known as Red Star Belgrade faced city rivals Partizan Belgrade in a fierce derby in front of about 16,000 people who watched from the stands, the largest gathering of such in Europe since the pandemic began.

The Serbian authorites has been relaxing lockdown rules and earlier in the month it announced that open-air gatherings with an unlimited amount of people can begin to take place.

Television channel RTS showed little sign of health guidelines in place at the match against Partizan Belgrade as well as at other match centres.

After the final game of the season against Proleter last Saturday, Red Star Belgrade celebrated their Serbian title triumph with over 10,000 of their fans.

In other not to risk things, the club made sure that at least four of the five players did not take part in the last match as they had felt coronavirus symptoms ahead of the game.

“The players feel well and are in strict isolation and in permanent contact with the medical team of the club,” Red Star said in a statement.

In the past week, Montenegro that had declared its state Coronavirus free reported new cases of coronavirus, with the government putting the blame on citizens who had attended the match in Belgrade (Serbia) and brought the virus back over the border.

“It is clear that the departure of our citizens to the football derby played in Belgrade has brought us to the situation we have today,” the head of the main hospital in Montenegro capital Podgorica Jevto Erakovic said on Thursday.

The Serbians saw their league resume on the 29th of May, at first behind closed doors, before the government further eased restrictions.
