Manchester City manager Pep Guardiola was on Friday charged by the Football Association over his wearing of a yellow ribbon in support of jailed Catalan independence leaders.
The FA said in a statement that the symbol sported by the former Barcelona boss on his jacket broke its rules.
“Pep Guardiola has been charged for wearing a political message, specifically a yellow ribbon, in breach of the FA’s kit and advertising regulations,” the FA statement said.
“He has until 6:00 pm (1800 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.
