Pep Guardiola is set to defy the Football Association and wear his yellow ribbon at Wembley on Sunday.
The Manchester City manager was charged for promoting a political message by way of support for jailed pro-independence Catalan politicians.
Guardiola, who has until March 5 to answer the charge, faces a fine or potentially a touchline ban if he continues sporting the ribbon.
He started pinning it to his coat and jumpers for matches and press conferences after Jordi Sanchez and Jordi Cuixart, who lead prominent separatist groups, became political prisoners.
