Paris St Germain forward Lionel Messi and three other players have tested positive for COVID-19 according to Statement from the French Ligue 1 club.
Argentina international Messi joined PSG from boyhood club Barcelona in August and the 34-year-old has scored six goals in 16 games in all competitions for the Parisian side.
Defender Juan Bernat, back-up goalkeeper Sergio Rico and midfielder Nathan Bitumazala were the other players who returned positive tests.
PSG said the four players were in isolation and subject to appropriate health protocols.
Mauricio Pochettino’s team are top of the Ligue 1 standings on 46 points after 19 matches, 13 points above second-placed Nice.
They are due to travel to third-tier club Vannes on Monday for a French Cup round-of-32 match.
“This is the risk with which we live, on a global scale,” said Pochettino.
“In football, contact is inevitable, we share the dressing room.
The risk of contamination is there, but we take all the necessary measures to try to prevent a player from infecting others.”
Pochettino said he was unsure if Messi, who is currently in Argentina, would feature in their next league game, at Olympique Lyonnais on January 9.
“Messi has been in regular contact with our medical team and when he has a negative test, he will travel to France, but we don’t know any more than that.
I don’t know if he will be involved against Lyon,” he said.
“Until he gets a negative test in Argentina, he will not be able to travel to France. So, it is all down to the test in terms of when he can travel … we will assess when he is ready to play.”
