Isco says that Real Madrid must learn from their mistakes after very nearly blowing a four-goal lead in Wednesday's Champions League win over Shakhtar Donetsk.
Rafael Benitez's men looked set to record a resounding victory in Lviv thanks to two Cristiano Ronaldo goals, as well as strikes from Luka Modric and Dani Carvajal.
However, the visitors went to pieces in the closing stages, allowing Shakhtar to score three times in the space of 11 minutes to set up a surprisingly tense finale.
Madrid ultimately held on to claim the win that sealed their progression to the last 16 as winners of Group A but Isco acknowledged that Rafael Benitez's men have work to do from a defensive and mental perspective.
"We played extremely well, not counting the final few minutes. We got the win and the three points," Isco told the official Madrid website.
"We have to try to correct the mistakes and continue working hard. We need to learn from our mistakes and we hope they will not happen again in the future, because in the Champions League they could end up costing us dearly."
