Nick Kyrgios joined plenty of Twitter users in criticising Novak Djokovic after the Serbian world number one tennis player reportedly wrote to Tennis Australia organisers asking them to ease quarantine restrictions for players.

Passengers who arrived on three charter flights for the Australian Open have been placed into hard quarantine, including more than 70 players who are unable to train outside their rooms for 14 days before the years first Grand Slam starts on February 8.

A Spanish tennis website reported that Djokovic wrote to Tennis Australia boss Craig Tiley with a list of demands, asking for reduced isolation periods and having players moved to private houses with tennis courts.
