Hernandez has already had a taste of Clasico controversy, having officiated the 2-1 win for Real Madrid at Camp Nou last season - a match which ended Barcelona's 39-game unbeaten run.
Madrid will be looking to a rejuvenated Cristiano Ronaldo, who has scored five in his last two appearances and netted his 100th Champion League goal with a hat-trick against Bayern Munich on Wednesday. In any case, if he doesn't, Zidane will not rush him and will wait some more time to have him completely ready for the Champions League semifinals.

For defenders they are remarkably prolific and it would not be unusual if, despite all the attacking talent on show at the Santiago Bernabeu on Sunday, one of them ended up settling the game. They will have got over the sizeable hurdles of Bayern and Barca and be heading for a possible historic double. That will be scant consolation if it's played out against the back drop of a Real Madrid winning La Liga and the Champions League.
