Athletic Bilbao boss Marcelo Bielsa apologised to referee Alejandro Hernandez after being sent off in his side's 2-1 win over Sevilla.
The Argentine Coach was sent to the stands after protesting a contentious decision in his team's victory at San Mames, but has admitted he was wrong to call into question the referee's integrity.
“There is no reason to protest as I did,” he told a Press conference. “I want to apologise to the referee and his assistants.
“I claimed that there was a handball and that is not in the regulations.”
He also commented on the gesture made by his opposite number Michel Gonzalez, as the Sevilla boss tried to speak in favour of the former Chile man.
“I have seen the gesture made by Michel. It was an act of chivalry, and I want to thank him for that.”
