Arne Slot allegedly told referee Michael Oliver "if we don't win the league, I'll f---ing blame you," in the aftermath of Liverpool's draw with Everton last month.
Slot was given a two match touchline ban by the Football Association (FA) and fined £70,000 ($88,500) after he was shown a red card during dramatic scenes following a late goal by Everton in the Merseyside derby.
Slot, who approached referee Oliver after a melee between the two sets of players following the full-time whistle had seen Everton's Abdoulaye Doucouré and Liverpool's Curtis Jones sent off for second bookable offences, admitted acting "in an improper manner and/or used insulting and/or abusive words and/or behaviour towards both the match referee and an assistant referee.
