Manchester City manager Pep Guardiola has been charged for breaching the FA’s kit and advertising regulations.
The Spaniard’s sanction is for “wearing a political message, specifically a yellow ribbon”, said the Football Association.
Guardiola said in November he wears the ribbon to support imprisoned politicians in Catalonia, where he was born.
He has until 18:00 GMT on Monday 5 March 2018 to respond to the charge.
The FA had spoken to Guardiola about the issue in mid-December and two formal warnings have been given which were ignored.
The charge was then triggered when he again wore it pitchside – he is free to wear it elsewhere – during City’s shock FA Cup loss against Wigan on Monday.

Guardiola had said in November: “If one day in prison was already too much, look how many days they’ve been there now.
“Like everybody knows, hopefully sooner or later I can stop wearing it (the ribbon).
“All the politicians that are in prison, I hope they can leave and go back home soon with their families and continue living the lives they deserve.”
