Former World Cup star Thomas Kahlenberg has tested positive for the coronavirus in the highest-profile case of the disease spreading to football.

After contracting the virus on a trip to Amsterdam, the 36-year-old is now in quarantine along with 13 members of Danish club Brondby's staff.

Among those reported by local media as being isolated are defender Joel Kabongo, club CEO Ole Palma and assistant coach Martin Retov.

Danish health services are now looking to get in touch with people Kahlenberg has been in contact with since he returned from the Netherlands, including fans directly nearby at Sunday's game between Brondby and Lyngby.

Three players from Lyngby's squad have also been placed in a 14-day quarantine despite showing no symptoms.

Martin Ornskov, Kasper Jorgensen and Patrick da Silva all came into physical contact with Kahlenberg and are beginning for a period of isolation.
