Bale's play (he is obviously hurt but he still gives poor effort most matches) or the fact that Zidane keeps going to the Bale well when he has Asencio (a much better compliment to Ronaldo), Isco, and James sitting on the bench. Until Bale is 100% healthy and shows a top level of fitness his behind should be glued to the pine.
The game yesterday was one for the ages. Navas seems confident again and TerStegen was the man of the match for Barca had it not been for the magic of Messi. Ramos got what he deserved and it killed my beloved Real Madrid. I still think Morata should be playing over Benzema as he delivered another below average performance and was ghost like until he got yanked.
