Lionel Messi is among four Paris St-Germain players to test positive for Covid-19.
The Argentine forward, defenders Juan Bernat and Nathan Bitumazala and keeper Sergio Rico were found to have Covid just a day before PSG’s French Cup tie against fourth-tier side Vannes.
The French club has said the quartet is isolating.
PSG’s first league game of 2022 after their winter break is against Lyon on Sunday, 9 January.
Forward Neymar will miss that match as he continues his recovery from an ankle injury in Brazil.
PSG say the 29-year-old is expected to return to training in three weeks.
