While quarantine in Melbourne has been capturing the headlines, players in Europe have become increasingly angry about the way self-isolation is being handled by the tennis authorities.
The story begins at the first ATP Challenger tournament of the year in Istanbul, a fortnight ago.
The day after the tournament got under way, players received a letter from the FFT which explained that anyone arriving in France from a country outside the European Union must now self-isolate for seven days.
Some players later received a phone call from the ATP to remind them of the rules.
The letter was very timely, as there was to be no exemption for elite athletes, and one of the two events on the schedule the following week was in the north-western French city of Quimper.
