The quartet are said to be isolating. PSG boss Mauricio Pochettino added that Messi remained in Argentina where he spent the winter break and would not travel until testing negative. During a pre-match news conference on Sunday, Pochettino said he could not put a date on Messi's return. 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.
