It was the first time in 73 matches Real had not scored as former Madrid goalkeeper Antonio Adan ensured his boyhood club went away empty handed and captain Sergio Ramos was also frustrated.
“It’s not normal in these matches at home against sides who on paper would normally be leaving the Bernabeu with a different result,” Ramos said.

“We had possession, chances.
“Last year we won some games we didn’t deserve to and this year it looks like the opposite but we can’t go mad about it.”
