Sergio Ramos insists Real Madrid will not "drive ourselves mad" after following up their Clasico win with defeat at Real Betis, but he acknowledged Sunday's match in Seville represented a huge missed opportunity.
Madrid took pole position in the Liga title race with victory over rivals Barcelona last week, only to fall back to second with a 2-1 loss at Betis after the Blaugrana's triumph the previous day.
Zinedine Zidane's side struggled to break down Betis and were fortunate to be level when Sidnei, the scorer of a brilliant opener, conceded a penalty that Karim Benzema dispatched.
