The time is certain (18:30 CET) but not the date. The match between Sampdoria and Inter is still not on the calendar even if the two most likely hypotheses are April 2nd and 3rd.
“TV is pushing for Wednesday to not have two events on the same day since Bayern-Juventus will be played on Tuesday. Inter, however, prefer to play on Tuesday because on Saturday night, they would have to return to the San Siro playing Atalanta. This match cannot be pushed back due to the Milan Marathon,” said the Gazzetta dello Sport
