Manchester City boss Pep Guardiola has claimed that Martin Glenn failed to understand the significance of his yellow ribbon stance after accepting a Football Association charge.
FA chief Glenn controversially likened the symbol - worn in support of jailed pro-independence Catalan politicians - to the Nazi swastika or an Isis logo.
Glenn, who has since apologised for his comments, argued that the ribbon could cause offence to others, but Guardiola insists that it is merely a symbol of solidarity.
Speaking at his pre-match press conference ahead of the Champions League meeting with Basel, which City lead 4-0 heading into the second leg, the Catalan coach said: "You say extraordinary comments? Mr Glenn apologised. My first impression when I heard that was he didn't understand exactly what the yellow ribbon means.
"It was simple like that. He made a comment that was far away from what it means. Maybe now he will realise what it means. It's not about independence or no independence. It's about four people who are in jail when they didn't do absolutely anything to be in jail for.
"I think with his comments he didn't understand the reality of what happened right now with the situation but I'm pretty sure now he will know it."
Guardiola has worn the yellow ribbon since November and is expected to sport it on his clothing against Basel, as UEFA has previously turned a blind eye to the subject.
