Tottenham boss Antonio Conte says Thursday's meeting between managers and the Premier League to discuss issues around the Covid-19 pandemic was like talking to a brick wall.
Three games on 26 December have now been postponed, taking the total to 13, while players and club staff returned a record 90 positive tests last week.
Asked if the meeting was a waste of time, Conte said: "I think so."
The Italian added: "Yesterday it was [like talking to] a wall and for this reason I also prefer to not go into it."
The Premier League has declined to comment and BBC Sport has been told Spurs boss Conte did not contribute to any discussions within the meeting.
