Sunday’s El Clasico referee Hernandez Hernandez is aiming to ‘minimise’ errors and admits the match is a ‘great responsibility’.
Hernandez took charge of last season’s El Clasico at Camp Nou which Real Madrid won 2-1 where he and his team were generally thought to have avoided controversy, but the game will be under the microscope.
"We watched it [the Clasico] afterwards to analyse it," Hernandez told AS.
"After every game you study your mistakes, and there are always mistakes, so as not to repeat them or minimise the possibilities.
"It is a privilege to do two Clasicos in a year. You can only enjoy the experience and hope the best team wins, and above all that it's not due to our mistake.
"We take all games with maximum professionalism, whatever teams are playing, but it would be a lie to say the Clasico is not special.
“Every player aspires to play in games like this, every fan wants to see them, and all referees want to experience it.
"It is a trampoline, a global shop window to show that we are capable and that we can get international opportunities. It is a challenge and a privilege and I recognise the responsibility.
“Real Madrid’s win over Bayern? I saw the game, I can also make mistakes. You can have better or worse games, but Kassai's CV and level are not in question. You can be critical but must have respect."
