Manchester City manager Pep Guardiola has been warned by the Football Association over his behaviour during Thursday's 2-1 victory against Liverpool.
An animated Guardiola threw his scarf to the ground and shouted at fourth official Martin Atkinson after a decision had gone against his team in the second half.
It is the 47-year-old's first warning and was posted on the FA website, which makes it clear that any manager receiving four such warnings must serve a touchline ban.
City moved to within four points of Premier League leaders Liverpool after the win at the Etihad Stadium.
