Marcelo has warned Real Madrid to learn from their mistakes following their 2-1 defeat to Valencia on Wednesday.
Simone Zaza and Fabian Orellana scored inside the first nine minutes at Mestalla, and although Cristiano Ronaldo halved the deficit, the visitors could not prevent a second LaLiga loss of the season.
Zinedine Zidane's side have now suffered three defeats this year - one more than they managed in the whole of 2016 - and remain only a point above Barcelona at the top of the table, although they have a game in hand.
"I think we started badly, there are no excuses," he said afterwards. "We're to blame, we played badly.
"We tried at the end but we conceded two silly goals and we made mistakes. We're still at the top of the table but we can't start games like that.
"Valencia are a great team, they've been through bad times but it's difficult to play here, the fans get on top of you. We'll learn from these mistakes so it doesn't happen again.
"We've done everything to get the equaliser, but we have to change a few things."
3 - Real Madrid have lost more games in 2017 (3) than they had last year (2 - all competitions). Alarm. February 22, 2017
