Barcelona coach Ernesto Valverde admits Ousmane Dembele's dismissal against Sevilla baffled him.
Dembele was sent off late in Barcelona's win for comments made to the referee just moments after Ronald Araujo was shown a straight red himself.
It has been reported that the Frenchman said "very bad, you're very bad" to the referee, which saw him given his marching orders.
"I don't know what he said," Valverde said when asked for his opinion in his post-match press conference.
"But I don't think it was too long a sentence.
"With the Araujo dismissal on his debut, it didn't seem like a foul to me.
"Then the Dembele one is a mystery."
Looking at the match as a whole, Valverde was understandably delighted to finish with such a comprehensive scoreline.
"It was a complicated and important game for us," he explained.
"They've had a lot of chances, but this is what it is.
"They left spaces and we had more punch, which proved key."
