Real Madrid midfielder Toni Kroos says they weren't at their best for victory over Barcelona.
Real won 4-2 on Sunday.
But Kroos says: "The truth is that it was not a good match in terms of level, it must be said. Both sides. Both made many mistakes and lost many balls. In reality it was a match that if we had played well, we could have beaten them 4-0. Really.
"They didn't have much drive, especially in the first half.
"We won 14 (Clasicos), drew 3 and lost 11. I verified it today.
"Sometimes I was behind. After three or four years I was definitely far behind, I even lost 4-0 at home. I think in the last two or three years we have won six or seven in a row."
