Pep Guardiola has become the first Premier League manager to be shown a yellow card.
The Spaniard was booked by referee Martin Atkinson in the 41st minute of the Community Shield encounter with Liverpool at Wembley on Sunday.
Guardiola was left furious after a high challenge from Joe Gomez left City skipper David Silva in a crumpled heap.
The Liverpool and England defender won a bouncing ball ahead of the Spaniard, but Guardiola was unhappy with the manner of the challenge, venting at fourth official Stuart Atwell.
As Silva received treatment on the field, referee Atkinson approached the technical area and proceeded to show the yellow card.
Rules to show managers yellow cards were brought in by the FA in 2018 to clean up touchline behaviour.
